collaborate efficiently. This makes it much easier for teams of programmers and designers Notes
to collaborate efficiently.
2. 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 precompiled
to byte-code and Just In Time (JIT) compiled when first requested. Subsequent requests
are directed to the fully compiled code, which is cached until the source changes.

3. Use Services Provided By the .NET Framework
The .NET Framework provides class libraries that can be used by your application. Some
of the key classes help you with Input/Output, access to operating system services, data
access, or even debugging. We will go into more detail on some of them in this module.
4. 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 you do in Visual Basic 6. And
you have full IntelliSense support, not only for your code, but also for HTML and XML.
5. State Management

To refer to the problems 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.

6. Update Files While the Server is Running
Components of your 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.
7. XML-Based Configuration Files
Configuration settings in ASP.NET are stored in XML files that you can easily read and
edit. You can also easily copy these to another server, along with the other files that
comprise your application.
Here are some points that give the quick overview of ASP.NET.
• ASP.NET provides services to allow the creation, deployment, and execution of Web
Applications and Web Services.
• Like ASP, ASP.NET is a server side technology.

• Web Applications are built using Web Forms. ASP.NET comes with built in Web Forms
controls, which are responsible for generating the user interface. They mirror typical HTML
widgets like text boxes or buttons. If these controls do not fit your needs, you are free to
create your own user controls.
• Web Forms are designed to make building web based applications as easy as building
Visual Basic applications.
