This is very similar to things we're looking at with a large C++ application with a 10 year history. We're looking at moving it to .NET, but with an app this large and old, a total rewrite is out of the question. I haven't found much information on this type of interop.

>Hi Claude. I agree with your comments about this, and I agree that more needs to exist to help educate VFP developers on how to use .NET with VFP in a combined environment, just like VFP is used together with SQL Server today. I am working on some things in this area to to help VFP developers add .NET to their existing skill set rather than focusing on .NET as a replacement for VFP. It would be great to see more training on the together topic. Most companies with VFP applications I talk to are more interested in interop and slow .NET adoption adding key features like ASP.NET based web based rather than a total rewrite from scratch.
