As I was reading, apparently the ability to group up classes similar to the .NET namespaces has been underlying all along. I don't think you can mix them inside each other like you can in .net, but that's not an important feature anyways.

I've never seen anyone do this though. Are there any known examples of this? For example the System.IO and System.Diagnostics groupings would be a common request.
So, I've built my own set of class collections for commonly used functions. All of them use the API to duplicate the .NET functions.

Is anyone interested in contributing classes to this project? Any interest in seeing this as open source?

I figured that some members here may be very against the notion of .Net, but this can help bring fresh code examples over into vb6.
The purpose of this is for back-porting the majority of .NET code to VB6. I realized that much of the common .NET classes can be done in VB6 with the API, rather than calling an Interop dll through.NET.
So I built a back-porter to help convert .net to vb6. While the vb6 classes are extended with .net capabilities to meet half way. The results are very good so far, and much less time consuming than porting it all by hand.
