In case it helps anyone, this was my original question on Stackoverflow that got me here:
The answer in my original question is what got me going. However, just yesterday, in an interview of a candidate, she gave me information aboutthe "XSD data contract importer":
I haven't tried that yet.
By "Pscyhic Software" is was referring to the apparent fact that there was no documentation, and that I have to be a psychic to figure out how to use it. My pet peeve with CodePlex projects in general are:
1) The home page doesn't clearly state the benefits and features of a tool. Even though owners of projects aren't selling them for money, they still need to explain why the tool is useful, what problem it solves.
2) The home page or the install should have at least a one page .doc or .pdf called "Getting Started" with at least a sample of what to do. Seems like you reference some blogs on your home page, but are they specific to how to run your tool?
Or just the general background of why the tool was neeed?
As to Biztalk schemas, they apparently have a somewhat "unique" or non-standard way of reference one to the other, which I have noticed some utilities don't seem to handle.
I'm no longer totally blocked (again, see what I did on Stackoverflow link above). So my research has moved from "must-know" to "nice-to-know". I hope to look into these issues more later.
