What is ASP.NET ?

 ASP.NET is a server side scripting technology that enables scripts (embedded in web pages) to be executed by an Internet server.

• ASP.NET is a specification developed by Microsoft to create dynamic Web applications, Web sites and Web services.
• It is a part of .NET Framework.
• The ASP.NET compiles the Web Pages and provides much better performance than scripting languages, such as VBScript.
• The Web Forms support to create powerful forms based Web pages.
• ASP.NET Web server controls to create interactive Web applications with the help of Web server controls, you can easily create a Web application.

ASP.NET introduces entirely a new object-oriented execution model. In order to overcome 
the limitations of ASP (Active Server Pages) , Microsoft has developed a new technology 
called Microsoft ASP.NET . ASP.NET is more than just the next version of ASP technology, 
using its mature programming languages VB.NET and C#.

ASP.NET is built on the Common Language Runtime (CLR), allowing programmers to write 
ASP.NET code using any supported .NET languages like VB.NET and C#. Unlike the ASP
 runtime, ASP.NET uses the Common Language Runtime (CLR) provided by the .NET 
Framework. The Microsoft .NET Platform provides all of the tools and technologies that are 
needed to build distributed Web applications. ASP.NET is integrated with Visual Studio .NET, 
which provides a GUI designer, a rich toolbox, and a fully integrated debugger. In ASP.NET, 
you can write the HTML code in the .aspx file and the code for programming logic in the
 code-behind file (.aspx.vb or .aspx.cs ). Also ASP.NET introduces two sets of controls, 
the HTML controls and the Web controls, which are collectively known as "server controls."
