One of our partners, RJS Software, is doing a training session in Dallas.  The session teaches AS/400 / RPG developers how to program in .NET and use the VS tools.   The focus is on using .NET to extend and modernize their AS/400 applications.  However, once they are familiar with the tools and capabilities it is common for them to start building new apps on the .NET platform.

Here is the URL for the training course:
