Silverlight Data validation problems

So - I spent today making one last ditch effort to get the built-in Silverlight data validation to work in my project, all to no avail. I even posted a question on Stack Overflow, and have yet to receive an answer, which is a first for me. I downloaded several of the samples, from Wildermuth, Liberty and others, and they none of them would work out of the box, they all either had strange dependencies or would throw errors on build. I finally gave up and did the validation manually, the most recent version is on the site now. Granted, I'm trying to do remote data objects, so my situation and the examples are a bit different, but it would be nice to have some degree of success with this.
