You would be better off ditching Micro$oft altogether. They love doing this kind of stuff to people. Just ditch them and ditch Vb.Net and go somewhere else for your programming tools.

Sorry, but that's nonsense. It's pretty clear that applications compiled against a *newer* version of a library won't work with older versions. Almost any .NET 2.0 application makes use of features which are not present in older versions of the .NET Framework. (Sure, there are differences in the CLR which prevent execution of .NET 2.0+-based assemblies on the .NET 1.* CLR.)

VB6-based applications didn't run on the VB5 runtime libraries too. But there is one significant difference: .NET 1.1-based applications will run on newer versions of the CLR, whereas an application developed using VB5 won't run on a system which provides the VB6 runtime files only.
