While this won't solve your immediate problem, it's important to understand the design-time features of the .NET Framework. Read Enhancing Design-Time Support[^] in the .NET Framework SDK for more details. Much of what you see in VS.NET when designing with forms and controls is actually provided by classes in the BCL. For integration like you want, see the Visual Studio Extensibility Center[^]. Also see the Automation and Extensibility Reference[^] in MSDN Librayr, which documents the DTE (Design-Time Environment) object model and gives C# and VB.NET (as well as C++, of course) examples. Whatever you read for VB (as in VB6), the same is pretty much true since the EnvDTE assembly is an interop assembly created from the typelib that automation clients like VB6 use to automate and object library. Specifically, you'll want to take a look at the VSProjectItem Object[^]. If you look in VS.NET's New Project dialog, you'll also see a couple of extensibility projects that serve as a good start.
