It is simple ,modern, object-oriented programming language.It is vary much based on DOS version called BASIC. BASIC means Beginners All-purposeSymbolic Instruction Code. It is a relatively easy programming language to learn and it is different from c#.net.It als have vb.net 2005 , vb.net 2008 , vb.net 2010 and latest is vb.net 2012.

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET Framework. Although it is an evolution of classic Visual Basic language, it is not backwards-compatible with VB6, and any code written in the old version does not compile under VB.NET.

Like all other .NET languages, VB.NET has complete support for object-oriented concepts.

All objects inherits from the base class Object.

• Modern, general purpose.
• Object oriented.
• Easy to learn.
• Structured language.
• It produces efficient programs.
• It can be compiled on a variety of computer platforms.
• Part of .Net Framework.
