Contains compiled code (.dll files) for controls, components, or other code that you want to reference in your application. Any classes represented by code in the Bin folder are automatically referenced in your application.
ASP.NET aims for performance benefits over other script-based technologies (including Classic ASP) by compiling the server-side code to one or more DLL files on the Web server.[21] This compilation happens automatically the first time a page is requested (which means the developer need not perform a separate compilation step for pages). This feature provides the ease of development offered by scripting languages with the performance benefits of a compiled binary. However, the compilation might cause a noticeable but short delay to the Web user when the newly-edited page is first requested from the Web server, but will not again unless the page requested is updated further.

The ASPX and other resource files are placed in a virtual host on an Internet Information Services server (or other compatible ASP.NET servers; see Other implementations, below). The first time a client requests a page, the .NET Framework parses and compiles the file(s) into a .NET assembly and sends the response; subsequent requests are served from the DLL files. By default ASP.NET will compile the entire site in batches of 1000 files upon first request. If the compilation delay is causing problems, the batch size or the compilation strategy may be tweaked.

I buy a tube of . I prefer what is called Ivory Black and white sweet mix that you add white to a large number of different colors to make lighter versions. From these basic colors you can make any color by mixing in exotic combination. Be creative and experiment. And do not be afraid of color, because color is most popular in museums! Gloss paints are historically the crowd favorites. Regarding the variety of colors from these basic colors, mix red and white to make pink, yellow blend with green to lime green, white with blue to , white and black to gray, etc. Use your common sense and play with him!

Keep your brushes soaking in a plastic cup to keep them clean and ready for your choice of color next .... and prevent them from drying out. Now, decide what you want to paint. Very important ... you do not need to know how to draw. That's the great thing about painting, you can create, even if you never had a lesson. Make no mistake, the art school is great. But do not let the lack thereof deter you create. You do not need a professor to tell you how to create. You do not need to know , but then let your imagination
soar! When deciding what to paint, go to other sites on Google or artists famous artists to inspire you. Again, do not let a lack of training dissuade you from painting! Many great artists of the past had no training whatsoever. Many can not draw stick figures, but they can paint because the colors give you ! You can also go to my sites listed below or Google me crazy all the work that I created. My personal preference was to create a wide variety of work to keep it interesting and versatile. I did not want to be the artist who painted a thing again and again. For me it is boring, and it should be annoying to you too. Every artist knows the past has a wide variety of work. You will also find it makes it more interesting to you while you do, because you'll never get bored, you will always wonder how it'll turn. Step Two: Now
about drawing on the canvas that you want to create in the . Do not worry, it does not have to be perfect. Your request fresh paint your innermost imagination, it will look good. If you mess with the pencil, just delete it off and start over.

Caution: resist the urge to simply copy an artist's painting of the past. This is the career suicide, and so boring. You're smart, do your own artwork. It's much more interesting and unique. A copy of a painting of the past just to make you look like an imitation, and who needs a resume? Remember, to decide what to paint is the hardest part. But once you get into , it will come to you, I promise. Painting from your own life is the best advice career as a painter. Truth is stranger than fiction anyway.

of red and call it . Be creative, go with the flow, not much thought. Paint what you want to paint and the world will eventually find it interesting. After all, it's your art. Painting nature is always a good idea, that nature never goes out of style. three: go online and study the basics of .

Before you have knowledge, it's complicated. But once you have it, it's easy! Knowledge is power, and this phenomenon certainly applies to painting. The technical aspects are the easy part of . Anyone can do it. You ultimately could be as capable as Monet with practice. We humans can do whatever we decide to do! Decide what to paint is the hardest part. It takes discipline and a desire to create a singularly focused picture after another. For some reason, I loved the minute I started. And I never looked back. I love it today as much as I did 16 years ago. I never "writer block" is that of painting. I just painted from my experiences in life. So do not think too hard for her. Paint the apple sitting on the table, or paint the tree in your own backyard, painting your girlfriend in an unusual way. But painting something that means something to you, that's all that matters. Make it funky, make it interesting. If it is abstract, remember that abstract art has long been the most desirable. It is an expression of , make it unique. For those who want realism, take a picture. What is amazing is that once you do, you realize that this is the ultimate escape in happiness.

Suddenly you forget your problems during this time period. You have control, and nobody can remove it once you're adept at painting. The process is addictive. But like anything, you should start! And once you do, look .... you'll be hooked. OK, let's go. The first step . You need a flat brush, a fan, a small detail brush and a couple of Filberts. A filbert brush is rounded edge that allows you to manipulate the paint easily without going outside edges. Ultimately buy brushes that you like, and make them work. Fans allow you to mix, for example. I use a lot of fans and that's how I graduated color throughout my images. Everything I paint is . not airbrush or assistants. I want to be an expression of me and nobody else. You also need an environment of oil paint to mix with the oil painting to more fluid, and to speed up or slow down the drying process. Whichever you prefer. Access to the art shop and not be afraid to ask for . they will love to help! A medium is simply a liquid additive that increases the brightness, makes it flow easily, retains the finish over time, it prevents yellowing. I personally like and Galkyd Galkyd Lite. If this is not available, buy a medium that looks like liquid amber and is a kind of thick. Do not buy watery mediums seek .... too hard to work with. The lite version of is simply thinner. I use it more than the other. I love it. Paintings I did 16 years ago using Galkyds look as pristine as the day I
painted them. You will also need a canvas and paint.

If not, try to manipulate the hair. Try cleaning, soak in turpentine, with scissors,
rubbing by. If after several attempts, it seems nothing good would result from the hair, tie a piece of cloth to the end and try to paint with it. Consider all the foolish things guitarists do for their effects pedals, tuning, amp settings, and so on. Do not throw away a brush once you have exhausted the means of saving.

Oil has long been a mysterious process of the public thought was relegated to a few and the eccentric. The artists and their lives have always been a rare breed, but painting a large number of original oil paintings was also a surefire way to conduct themselves in immortality. The paintings will always be there, traveling through history, with your name on it! So by this definition, there is certainly a noble profession. Think of .

and the market in the world, the artists do not have to starve more. I'm not starving, and I'm making money doing what I love.

But this article will put you on your way to experiment and have fun with paint. Ultimately it's like anything in this world.

This article describes some unorthodox methods to use brushes to paint in oils. None of these are intended to . It is more a list of additional things to consider when painting, and hopefully get results. It may or may not be relevant to your method, but I hope for some, it is interesting and even useful to consider. This article is perhaps more relevant to artists working in a relatively uncontrolled and rough. Cheap brushes are often rejected for failure to retain their shape, and leaving behind loose hairs in the paint. I found the more expensive brushes are okay, although I admit some are useless. Being so cheap, it is affordable to experiment with different brands and throw away the bad, taking note not to
. I have some expensive brushes that I keep separate, and use when needed. But mostly, I use the cheap. I do not know what is the difference between oil and acrylic brushes is, but my favorite brushes for oil painting are acrylic brushes. They seem to last as long, face painting fine oil, and are . It is often advisable to only
slightly dip the tip of the brush in the paint, so that no clogs up the shell. It is often said that, after dipping the brush into the paint, any excess should be wiped off the brush and bristles molded as needed. These recommendations make sense, but
I find taking this level of care all the time too boring and sometimes restrictive. As important as taking care of your brushes is, I advise you not to let artists take over, or affecting . At the end of the day, it's just a brush. Featuring painting, and produce the best work of art is the priority. Have hair to the ferrule clogged with the previous color, can sometimes be a good thing. I usually create my current color with paint color before. This is a very useful piece of advice I had a couple of years, and helped bring my colors. If you use this method, the brush and push relatively hard to the canvas, so that the previous color is applied to the shell along with the current colors can then be worked in to . Much of my shadow came about by doing this. It is not very controlled, but even if it does not work, the oil is fairly easy to fix. Rinsing the brush in turpentine between colors in only partially successful in removing the previous color, even if you do not clog up the hair. Notice that the turpentine itself becomes blurred very easily. I still have many of each type of brush in hand, if I want to start painting a new color and lighter, I can use a different brush. Do not throw away brush automatically if the paint has dried in the bristles by . Try it and see if it leaves a useful effect or texture.

[edit] Directory structure

In general, the ASP.NET directory structure can be determined by the developer's preferences. Apart from a few reserved directory names, the site can span any number of directories. The structure is typically reflected directly in the URLs. Although ASP.NET provides means for intercepting the request at any point during , the developer is not forced to funnel requests through a central application or front controller.

The ASPX and other resource files are placed in a virtual host on an Internet Information Services server (or other compatible ASP.NET servers; see Other implementations, below). The first time a client requests a page, the .NET Framework parses and compiles the file(s) into a .NET assembly and sends the response; subsequent requests are served from the DLL files. By default ASP.NET will compile the entire site in batches of 1000 files upon first request. If the compilation delay is causing problems, the batch size or the compilation strategy may be tweaked.

ASP.NET encourages the programmer to develop applications using an event-driven GUI model, rather than in conventional Web-scripting environments like ASP and PHP. The framework combines existing technologies such as JavaScript with internal components like "ViewState" to bring persistent (inter-request) state to the inherently stateless Web environment.

Other differences compared to ASP classic are:

    * Versions of ASP.NET prior to 2.0 were criticized for their lack of standards compliance. The generated HTML and JavaScript sent to the client browser would not always validate against W3C/ECMA standards. In addition, the framework's browser detection feature sometimes incorrectly identified Web browsers other than Microsoft's own Internet Explorer as "downlevel" and returned HTML/JavaScript to these clients with some of the features removed, or sometimes crippled or broken. In version 2.0 however, all controls generate valid HTML 4.0, XHTML 1.0 (the default) or XHTML 1.1 output, depending on the site configuration. Detection of standards-compliant Web browsers is more robust and support for Cascading Style Sheets is more extensive.

More than likely, it is probably what inspired the title of the painting. Whether you're a new artist, or an experienced artist, you should spend enough time planning this small area in your painting. I say small, because it should rarely be more than a fraction of the overall work (some say any more than the sixteenth), but it should be the most intriguing part. Imagine this, you want to paint a landscape scene where the light is filtered through the trees to create a patch Sun dappled in a small clearing of grass. Compensation is close to a small stream from which a young fawn drinks.

PHP is a general-purpose server-side scripting language originally designed for Web development to produce dynamic Web pages. It is one of the first developed server-side scripting languages to be embedded into an HTML source document, rather than calling an external file to process data. Ultimately, the code is interpreted by a Web server with a PHP processor module which generates .  It also has evolved to include a command-line interface capability and can be used in standalone graphical applications.[2] PHP can be deployed on most Web servers and also as a standalone shell on almost every operating system and platform free of charge.[3] A competitor to Microsoft's Active Server Pages (ASP) server-side script engine[4] and similar languages, PHP is installed on more than 20 million Web sites and 1 million Web servers.

This landscape sketch colors and sketches for learning and training based on the performance of the relationship between emphasis on composition, perspective, shape and color different from the Chinese Landscape Paintings. In the 20th century, through the efforts of many artists, landscape sketch with Chinese landscape painting sketch in the spirit of the national temperament and charm, combined with, such as can be seen in Western art of painting in the works of
. After a century of exploration and development, landscape sketching system in China has formed a complete set.

Constantly updated, with the concept of art, landscape sketching and traditional sketching concept, development to the creation of the "Sketch", a variety of new artistic ideas and colorful painting style, we feel a burst of fresh the art of the wind. Requires constant innovation and development of art, art should reflect the mental outlook of the times, but nowadays confused "ideas" and painting "form" landscape sketch is facing two major issues to solve: First, how to treat "technology 'problem. "concept" is a person's worldview and artistic aesthetic orientation,

 "technology" to solve specific screen. traditional landscape sketch in the observation of expression has formed a complete set of their own system, but if we rigidly treatment of "traditional", it is easy to fall into the "thousands of people side" of the sketch routine, the landscape face of inbreeding, self-repetition, self-copy, due to various reasons, this phenomenon in our country has been going on for a long period.

 art should reflect characteristics of the times and spirit of the traditional "concept" may be correct in that era, the fashion, but with the forward development of the times, the traditional concept may not be able to adapt to the aesthetic requirements of a new era of the new features of the times and spirit,

if such it may art of the narrow impoverished. one-sided exaggeration "the concept of" meaning, it ignored the richness of the works, crowding out the emotional taste, so that the work boring, poor and pale from life requires a certain skill, technical ability. With changing perceptions of skills and technology is bound to make appropriate improvements. We want to inherit, learning traditional sketching techniques, useful things in technology,

casting we need new skills, different skills and their predecessors in practice, inheritance and innovation are two sides of the same process, like biological species, genetic variation, the two sides of the same reproductive process. From this perspective, the first study skills or hands-on production of the order is not the main problem, as long as interest Bo Bo passionately done on the line should be said that the technique is important,

and cancel it also aerial art expression, but should not be overlooked is the "quality is better than the text" side, after all, is art. in a state of high quality is better than the text works in the present painting, rare, but too many examples to the contrary. picture of the painting is not the scenery but "Dealing with the skill of the landscape". Binhong talk about "heart" things in the painting, without painting "technology."

new ideas are not "out of nothing", it must be traditional and modern combination of derivative techniques should also be in a deep technical basis of in emotional domination under the new development.

whether "the concept of 'how to update the" concept "should reflect the tomb of the characteristics of landscape painting, that certain image characteristics of the natural world landscape, color, language can convey aesthetic. "Technology" but also in the expression for the screen at the same time, should be more emphasis on the spiritual power of the artist's emotional performance and screen, the only way of painting works will it be possible to have a spiritual and aesthetic rich connotation.

The gradient of the landscape sketching concepts and technologies, by the influence of the times, the age of works marked by the imprint of history forward. It should provide people with a long cultural tradition, should be full of the charm of the nation, should shine artists distinctive artistic offerings,     

but also a new technology, the effective use of new materials on the screen, and ultimately reflects the survival status of the modern , spiritual painting appearance and aesthetic appeal. We are pleased to see that the contemporary landscape painter who is exploring the landscape sketch of thorns on the road to forge ahead. We have reason to believe that the near future, you will see the advent of the more outstanding landscape painting works.

 Performance landscape is diverse, sketching landscapes occupy an important position in the art. Sketches directly to the face of a natural kind of art, in the face of real images sketching different teeth, memory and creative landscape. Sketching is the people into an experience of nature: the spiritual world and the high degree of integration of the natural world, the concept of human communication with the objective certain things King symbol image be revealed.

"Heaven and a 'is to emphasize the subjective spirit of the people is the height of the external culture and arts of ancient China by the influence of this concept, the idea will landscape creation that led to first before painting Thought Wei Landscape Paintings "tactic" "Where the painting landscapes,

intended at the pen." that means before painting, in the face of natural phenomena, to the will of the individual thought in advance to make thinking, not things without thinking and rashness random painting is because of the subjective 'means certain image characteristics of the objective state may be used to raise the artistic inspiration and interest.

 With this 'meaning' the overall situation in the chest, put pen to paper will be able to keep their God, specifically one of "like" subject to "means" for the meaning and use. Zhang Yan far in art history in mind, "also made the images will is the shape of the shape to be the whole of its backbone,

the backbone of the shape of Bong both in conception and go almost a pen. "conception" and "emotional" argument, emphasizing the subjective feelings of the artist's role in the creation, is a symbol of artistic practice and correct summary of the laws of .

 The pursuit of art in landscape sketching the spiritual connotation of the concept of the theory of traditional Chinese landscape painting, in essence, is the same.

Although the landscape sketching screen image, color, etc. of individual artistic outlook, manifested in many forms, and the artist's ideological and artistic level can also be seen the gap,

but the artistic creation of the subjective forces of the formation of landscape painting in the most strong vitality of the arts the. Admittedly, when the human society into the 21st century, the concept of creative forms of arts and culture is undergoing change. This art landscape sketch is also faced with traditional and modern,    

to maintain the old system of sketching or create new artistic ideas and outlook the challenge. Landscape sketch was introduced to China from the West since the early 1900s, due to its distinctive artistic features will soon be accepted by the people, and included in the research programs of the Academy of Fine Arts.

Varied and image, nature images presented the face of ten thousand kinds of style, Bright colors, the spiritual life of mankind to bring immense pleasure and enjoyment. Understand the nature of the landscape, we will find the landscape of the United States is generated by the image and the color, the image change of scene in the rhythm of color changes created the beauty of the scenery from the viewing angle. The heart and soul of America kidnappings, people enthralled. Therefore, the charm of the landscape has attracted numerous artists to depict it, praise it, and create the landscape of independent art, varieties.

Ancient times the performance of the symbol of the landscape art. Of the many rock paintings have been found on ancient people to their own impression of the nature of things King carved in stone. Found in Shaanxi Xianyang eastern outskirts of Qingong sites incomplete murals can be seen painted pavilion, plants, mountains and other scenery scene. China's earliest extant paintings depicts the landscape is a landscape painting of the Sui Dynasty Qian exhibition "Spring Outing",

the screen performance of the visitors in the warm sunshine of spring travel scene. Scenery sight of these works show, we can see the , in paintings have begun to pay attention to the performance of people and the natural environment, this after the Chinese landscape painters very careful to observe the characteristics of natural scenery, and feel the art and landscape features combine ,

creating a landscape high art realm. From the Tang Dynasty, Wang Wei, "The Kingdom Snow map, Song Jing Hao's" chronicle Map Yuan Dynasty, Huang Kung-wang, "Fuchun Mountains" painting can be seen through the screen, the painter expression of the natural features of the profound feelings. Chronicles painter unremitting efforts and the pursuit of the Chinese landscape painting and the theory formed their own unique artistic outlook and systems, and laid a solid foundation for today's artistic practice of the landscape.

Western landscapes with Chinese landscape painting - the same also has a long historical and cultural traditions. The landscape is the more important kinds of painting in . Western landscape watercolor, oil painting as the main body. The tradition of landscape painting in the West focus on depicting the natural world scene and color authenticity, emphasis on material King's perspective,

the accuracy of the proportional relationship. The screen presented to the audience is the realism of the natural features, and the viewer on the screen to produce a presence, thereby promoting the viewer's visual and emotional integration into the landscape of the "real" time and space. There are obvious differences of Chinese and Western traditional art of painting traditional Chinese painting art focus on the creation of the

in the West focus on the manifestation of objective spiritual world, the difference kept different from their own philosophical ideas. Despite the differences, but the art of both the source of a rule and spiritual strength is the same, on the landscape in terms of both stressed the natural state of the subject and object concepts, landscape performance are inseparable from the body appear, should have a uniform color screen, otherwise, there would be no landscape art.

Panorama in China after 10 years of development has to take the minister a very big success. In order to give full play to the panorama of the huge role it received good social and economic benefits, we should panorama hall, topics and other aspects of a need to explore. The panorama and build a museum location is very important. China panorama operating status analysis, the difference of its existence, in addition to the fixed factors, some panorama pavilion built in the location is too remote, or transportation is not convenient, long-term in the past is bound to affect the number of visitors. Panorama Museum in the choice of built site, as far as possible to build in urban areas, or transportation facilities, close to the attractions of the place, but should also step up publicity efforts for the .

 China is a vast country with a long history, rich in natural scenery and cultural history, we are fully qualified to engage in some novel and unique panorama, panorama more colorful in content and form, in order to avoid the current panorama creation exists The subject matter close to a similar problem. Such as the panorama of the performance of the ancient theme of the "Battle of Red Cliff" well, its emergence into a fresh, rich Chinese characteristics. We panorama should be promoted more than the creation of the characteristics of .

China panorama development efforts to broaden the panorama hall select and content topics. China's large land area, a large population, some of the outlying provinces, many people do not have the strength of the journey, to consider the points cast in the panorama hall site, do not build too much in one area panorama Museum to try to average panorama Building built in the provinces and regions, so that the National People can view this work of art.

Suggested that the relevant state departments to set up the management and guidance of the public art institutions, the panorama, the city, including sculptures and murals and public art planning, establishment, creation, development, research and other work tube. Panorama of the creative work, but also the introduction of the bidding mechanism, more creation units, more creative solutions successful, this will reduce some of .

The development of China's panorama is a long-term undertaking that requires the unremitting efforts of several generations, if the lack of long-term planning, it will affect the panorama career development. 2l century, with the further development of China's culture, arts, science and technology,

but we should also further expand the panorama performance theme. Of panorama creation in artistic and personalized needs further exploration, not style conceptualization. In fact, the breadth of the panorama painting art performance space We have the ability to avoid such a "close relative" creative. The panorama of art and design should reflect the personality, the distance from one another personality. But some panorama is obvious in the design conceptualization. Panorama Laiwu campaign in the design of the lack of personality. The screen is

, the lack of vertical and horizontal rhythm varied relations. Battlefield pyrotechnics layout design is also more scattered. Panorama Jinan Campaign "is a very good work, unfortunately, is painting some figures the proportion of the size of the design error, and even the shape is not accurate enough to make this outstanding works is there is a flaw. The overall color of the panorama, the environment, the characters portrayed style should be highly uniform, should not be differences.

Panorama Chungchon banks to surround and annihilate war ", the enemy flight Highway Department, our army to surround and annihilate at at Longyuan check, three obvious color change can be seen that the habit of . Panorama the Yuncheng battle ", figure painting style is also inconsistent. In the army to attack the city Department acted in a typical personal style of a northeast painting home. This panoramic view of the requirements of the unified realist style very consistent, resulting in the visual sense of discomfort.

Panorama of plastic design inadequacies in modeling the lack of a more natural transition, the proportion of production of plastic placed on the model size is inaccurate, and some vehicles, artillery produced too large or too small, and the picture objects in perspective the relationship between convergence on. What is more, some built the museum out of the panoramic exhibition, without the consent of the creative team agreed to had, without increase in the plastic on the various models, not only production model texture,

The panorama should focus on maintenance issues. Visit and flow of the daily panorama facing the crowd, the temperature difference between the climate of four seasons, hall ventilation, etc., will damage the panorama to a certain extent. The panorama is based on the materials for oil painting, painting medium color with a lot of

ASP.NET is a Web application framework developed and marketed by Microsoft to allow programmers to build dynamic Web sites, Web applications and Web services. It was first released in January 2002 with version 1.0 of the .NET Framework, and is the successor to Microsoft's Active Server Pages (ASP) technology. ASP.NET is built on the Common Language Runtime (CLR), allowing programmers to write ASP.NET code using any supported .NET language. The ASP.NET SOAP extension framework allows ASP.NET components to process SOAP messages.

[edit] History

After the release of Internet Information Services 4.0 in 1997, Microsoft began researching possibilities for a new Web application model that would solve common complaints about ASP,

The initial prototype was called "XSP"; Guthrie explained in a 2007 interview that, "People would always ask what the X stood for. At the time it really didn't stand for anything. XML started with that; XSLT started with that. Everything cool seemed to start with an X, so that's what we originally named it."[1] The initial prototype of XSP was done using Java,[3] but it was soon decided to build the new platform on top of the Common Language Runtime (CLR), as it offered an object-oriented programming environment, garbage collection and other features that were seen as desirable features that Microsoft's Component Object Model platform did not support. Guthrie described this decision as a "huge risk", as the success of their new Web development platform would be tied to the success of the CLR, which, like XSP, was still in the early stages of development, so much so that the XSP team was the first team at Microsoft to target the CLR.

With the move to the Common Language Runtime, XSP was re-implemented in C# (known internally as "Project Cool" but kept secret from the public), and the name changed to ASP+, as by this point the new platform was seen as being the successor to Active Server Pages, and the intention was to provide an easy migration path for ASP developers.[4]

Mark Anders first demonstrated ASP+ at the ASP Connections conference in Phoenix, Arizona on May 2, 2000. Demonstrations to the wide public and initial beta release of ASP+ (and the rest of the .NET Framework) came at the 2000 Professional Developers Conference on July 11, 2000 in Orlando, Florida. During Bill Gates' keynote presentation, Fujitsu demonstrated ASP+ being used in conjunction with COBOL,[5] and support for a variety of other languages was announced, including Microsoft's new Visual Basic .NET and C# languages, as well as Python and Perl support by way of interoperability tools created by ActiveState.

Once the ".NET" branding was decided on in the second half of 2000, it was decided to rename ASP+ to ASP.NET. Mark Anders explained on an appearance on The MSDN Show that year that, "The .NET initiative is really about a number of factors, it's about delivering software as a link building service, it's about XML and Web services and really enhancing the Internet in terms of what it can do ... we really wanted to bring its name more in line with the rest of the platform pieces that make up the .NET framework."[4]

After four years of development, and a series of beta releases in 2000 and 2001, ASP.NET 1.0 was released on January 5, 2002 as part of version 1.0 of the .NET Framework. Even prior to the release, dozens of books had been written about ASP.NET,[7] and Microsoft promoted it heavily as part of its platform for Web services. Guthrie became the product unit manager for ASP.NET, and development continued apace, with version 1.1 being released on April 24, 2003 as a part of Windows Server 2003. This release focused on improving ASP.NET's support for mobile devices.
[edit] Characteristics
[edit] Pages

ASP.NET Web pages, known officially as Web Forms,[8] are the main building block for application development.[9] Web forms are contained in files with an ".aspx" extension; these files typically contain static (X)HTML markup, as well as markup defining server-side Web Controls and User Controls where the developers place all the required static and dynamic content for the Web page.

Additionally, dynamic code which runs on the server can be placed in a page within a block <% -- dynamic code -- %>, which is similar to other Web development technologies such as PHP, JSP, and ASP. With ASP.NET Framework 2.0, Microsoft introduced a new code-behind model which allows static text to remain on the .aspx page, while dynamic code remains in an .aspx.vb or .aspx.cs or .aspx.fs file (depending on the programming language used).[10]
[edit] Directives

A directive is special instructions on how ASP.NET should process the page.[11] The most common directive is <%@ Page %> which can specify many attributes used by the ASP.NET page parser and compiler.

Can you really pull this off? You can if you have a clear understanding of color, saturation, contrast values, forms of leadership, and hard and soft edges. You are a licensed artist and you can create anything you can imagine. If this is true or not, that you must believe before attempting the work of art. Imagine the difference of the scene being shot instead of paint. In a photograph, the deer will always be the focal point, but in many cases the focal point of a photograph is not nearly as captivating as a good painting. Why? It is because a picture has details throughout the image. These details tarnish the focus. If you have any doubt about it, also paint the details throughout the painting and see how you confuse the viewer and dilute the main focal point.

Programmers can also build custom controls for ASP.NET applications. Unlike user controls, these controls do not have an ASCX markup file, having all their code compiled into a dynamic link library (DLL) file. Such custom controls can be used across multiple Web applications and .
[edit] Rendering technique

ASP.NET uses a visited composites rendering technique. During compilation, the template (.aspx) file is compiled into initialization code which builds a control tree (the composite) representing the original template. Literal text goes into instances of the Literal control class, and server controls are represented by instances of a specific control class. The initialization code is combined with user-written code (usually by the assembly of multiple partial classes) and results in a class specific for the page. The page doubles as the root of the control tree.

Actual requests for the page are processed through a number of steps. First, during the initialization steps, an instance of the page class is created and the initialization code is executed. This produces the initial control tree which is now typically manipulated by the methods of the page in the following steps. As each node in the tree is a control represented as , the code may change the tree structure as well as manipulate the properties/methods of the individual nodes. Finally, during the rendering step a visitor is used to visit every node in the tree, asking each node to render itself using the methods of the visitor. The resulting HTML output is sent to the client.

After the request has been processed, the instance of the page class is discarded and with it the entire control tree. This is a source of confusion among novice ASP.NET programmers who rely on class instance members that are lost with every page request/response cycle.

ASP.NET applications are hosted by a Web server and are accessed using the stateless HTTP protocol. As such, if an application uses , it has to implement state management on its own. ASP.NET provides various functions for state management. Conceptually, Microsoft treats "state" as GUI state. Problems may arise if an application needs to keep track of "data state"; for example, a finite-state machine which may be in a transient state between requests (lazy evaluation) or which takes a long time to initialize. State management in ASP.NET pages with authentication can make Web scraping difficult or impossible.
