Just came across SubSonic. It seems to be one of the best free .NET OR-mapper around the world. I’m playing with it, but as my Visual Studios are a bit crappy these days(to much bètas) it isn’t going so fast as it should be.
Nice to see is that the Sonic-guys spent a lot of time on webcast on their website. Browsing more across their website I’m getting more excited about this product 
. Here, a last free commercial with the abilities of SubSonic:
