I’ve been working on a validation framework for Dynamics CRM 2011.  I’ve published the first cut of the code.  It’s a little rough still, but I’ve been promising the sample to a few customers so I wanted to get the first working version out there.  Right now, it only supports regular expression validation.  However, if you read the home page, you will see how you can get involved in shaping the future of the sample.

Here’s a video walkthrough of the functionality.

I’ll also be recording a “getting the code to build” and code walkthrough video.  For now, if you want to try to get the code to build, ensuring you have NuGet installed and the Async CTP should do it.  However, I haven’t had time to test it on a clean machine so the “works on my machine” disclaimer applies.
