Introduction To ASP.NET

ASP.NET INTRODUCTION

ASP.NET is a web application framework developed and marked by Microsoft to allow programmers to build dynamic websites, web application  and web services. It was first released in January 2002 with version 1.0 of the .NET framework, and it is 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.

Advantages Of ASP.NET

• Separation Of Code From HTML :- 

                                                                    To make a clean sweep, with ASP.NET we have  the ability to completely separate layout and business logic. This makes it much easier for teams of programmer and designers to collaborate efficiently.

• Support For Compiled Languages :-

                                                                   Developer can use VB.NET and access features such as strong typing and object – oriented programming. Using compiled languages also means that ASP.NET pages do not suffer the performance penalties associated with interpreted code. ASP.NET pages are pre-compiled to byte-code and Just In Time(JIT) compiled when first requested Subsequent request are directed to the fully compiled code, which is cached until the source changes.

• Use Services Provided By The .NET Framework :-

                                                                    The .NET Framework provides class libraries that can be used by our application. Some of the key classes  help us with input/output, access to operating systems services, data access  or even debugging.

• Graphical Development Environment :-

                                                                   Visual Studio.NET provides a very rich development environment  for web developers. You can drag and drop controls and set properties the way we do in Visual Basic and we have full IntelliSense support, not only for our code, but also for HTML and XML.

• State Management :-

                                          To refer the problem mentioned before, ASP.NET provides solutions for session and application state management. State information can, for example, be kept in memory or stored in a database. It can be shared across Web farms, and state information can be recovered, even if the server fails or the connection breaks down.

•  Update Files While The Server Is Running :-

                                                                      Components of our application can be updated while the server is online and clients  are connected.  The Framework will use the new files as soon as they are copied to the application. Removed or old files that are still in use are kept in memory until the clients have finished.

• XML-Based Configuration Files :-

                                                                  Configuration  settings in ASP.NET are stored in XML files that we can easily read and edit. We can also easily copy these to another server, along with the other files that comprise our application.
