Visual Basic .NET or VB.NET, is an object-oriented computer programming language that can be
viewed as an evolution of the classic Visual Basic (VB),
which is implemented on the .NET Framework. Microsoft currently
supplies two main editions of IDEs for developing in Visual Basic: Microsoft Visual Studio 2010, which is commercial software and Visual Basic Express Edition 2010, which is free of charge. The command-line compiler, VBC.EXE, is installed as part of the freeware .NET Framework SDK. Mono also includes a command-line VB.NET compiler.
