Visual Studio .NET

Visual Studio .NET is the third major version of Visual Studio, released alongside the .NET Framework 1.0 on 13 February 2002. It rewrote all languages, and the development environment, to take advantage of the .NET Framework. It also introduced a new programming language: C#

Main changes
The main interface uses the name "Microsoft Development Environment", which was used until Visual Studio 2005. The main process is now, which was previously used by Visual InterDev. Also, to focus on .NET development, and to differentiate this version with the previous one, all languages have a .NET moniker, which would be removed in Visual Studio 2005
