I'm not sure I can provide much of value, but I'll tell you how I want to use it: MS has provided a sample project that allows you to do UI forms design, and the code that is generated can be XML (bleh), or in source code (e.g. form.Designer.language) if the CodeDom is present. So I was thinking if I could just wire the Cobra CodeDom in instead of the VB.Net or C# CodeDom, then voila, a UI designer for Cobra
So I could give it a try, and let you know the issues I encounter, but I'm not familiar w/ the CodeDom model itself, so couldn't give good feedback. Also, is your CodeDom MIT licensed?
