What is ASP.NET
ASP.NET is a unified Web development model that includes the services necessary for you to build enterprise-class Web applications with a minimum of coding. ASP.NET is part of the .NET Framework, and when coding ASP.NET applications you have access to classes in the .NET Framework. You can code your applications in any language compatible with the common language runtime (CLR), including Microsoft Visual Basic, C#, JScript .NET, and J#. These languages enable you to develop ASP.NET applications that benefit from the common language runtime, type safety, inheritance, and so on.
ASP.NET includes:
A page and controls framework
The ASP.NET compiler
Security infrastructure
State-management facilities
Application configuration
Health monitoring and performance features
Debugging support
An XML Web services framework
Extensible hosting environment and application life cycle management
An extensible designer environment
