We are currently in the process of converting from VB6 to VB.NET.  We are eventually converting all of our program over to use StrataFrame and .NET, but for now we only have part of it done.  We have taken out the administrative functions and created a StrataFrame app with a separate MDI.  We want to open up this AppMain instance or something similar when we select the appropriate menu option in the VB6 app.  What is the best way to go about doing this?  I've done something like this before with an ActiveX EXE, but that no longer exists in .NET....not sure what the equivalent would be or how any of this would affect the functionality of AppMain in a StrataFrame app.  Please offer suggestions.
