We use VFP and .NET together in Arnica WebPlatform (www.arnicacorp.com) for a few years now. Projects allow mix of programming code (VFP, C#, VB.NET, and also PHP) in one report, form, etc. For example, in the report, column A may have style script written in VFP, while column B may use style script written in C#. It works great.
