I think there is a separate VB namespace in the .NET framework, so VB-specific stuff could go there if necessary. Of course, there are already differences in the IDE between VB and C#, and that trend will continue. When it's all said and done, it sounds like VB may end up being the more attractive of the two for VFP developers.
