Visual Studio 10 and .NET Framework 4.0 is under development and will arrive in 2010. The technology preview is available (VS 10 on a Windows 7 image) and some documentation is also already available. One new cool feature is MGrammar, a grammar modeling language for constructing language syntaxes, a bit like the good old Gold Parser written in VB6.
Microsoft has an introduction to MGrammar on MSDN, and my friend Roger Alsing quickly made a .NET language, Mg Basic, using MGrammar. Check it out!
