[edit] What is .NET?
.NET is a sofware development platform created by Microsoft, focusing on web-oriented platform independent rapid application development (RAD). The .NET Framework classes provide a large API comparable to that of Java.
Many languages have compilers for .NET, but two main ones are Visual Basic .NET and C#. .NET languages are compiled to a platform independent language. When a .NET program is executed, it is converted to native machine code by the platform's CLR, or Common Language Runtime.
Being a Microsoft standard, it was originally a Windows only language. Today, projects exist to port it to Unix Platforms, chief among them is Mono.
