VB6 Driver step into .NET DLL

[PJSimon]

I've done it before, but now I forget how I did it!

How do you run a VB6 Application with a reference to a DLL written in .NET
and step into the .NET DLL interactively? The way I remember doing it, I had
both VB6 and VB.Net open with the VB6 Driver and .NET DLL running in each,
respectively.

Thanks!
