The goal of the project is to help designers and UI developers learn new technologies by relating concepts and skills in a visual way from one technology to another.
One of the first areas this site has focused on is helping bridge the gap for those transitioning from Flash to Silverlight. There is a great guide on the site titled “Flash to Silverlight Guide” that walks through concepts in Flash and applies them to how they are tackled in Silverlight.
OK, so why am I telling you all of this if its focused on Flash developers? Good question, so let me get to my main point. The site is NOT just for Flash developers. It also has some awesome content for getting up to speed on Silverlight development aspects you use (or should use) every day. Got your attention? Good!
