Easy Programming Model.  ASP.NET makes building real world Web applications dramatically easier.  ASP.NET server controls enable an HTML-like style of declarative programming that let you build great pages with far less code than with classic ASP.  Displaying data, validating user input, and uploading files are all amazingly easy.  Best of all, ASP.NET pages work in all browsers -- including Netscape, Opera, AOL, and Internet Explorer.

Flexable Language Options.  ASP.NET lets you leverage your current programming language skills.  Unlike classic ASP, which supports only interpreted VBScript, C#, and JScript, ASP.NET now supports more than 25 .NET languages (including built-in support for VB.NET, C#, and JScript.NET -- no tool required), giving you unprecendented flexibility in your choice of language.

The Enterprise versions of Visual Studio.NET deliver life-cycle features to help organizations plan, analyze, design,  build, test, and coordinate teams that develop ASP.NET web applications.  These include UML class modeling, database modeling (conceptual, logical, and physical models), testing tools (functional, performance and scalability), and enterprise frameworks and templates, all available within the integrated Visual Studio .NET environment.

Rich Class Framework.  Application features that used to be hard to implement, or required a 3rd party component, can now be added in just a few lines of code using the .NET Framework.  The .NET Framework offers over 4500 classes that encapsulate rich functionality like XML, data access, file upload, regular expressions, image generation, performance monitoring and logging, transactions, message queuing, SMTP mail, and much more!
