Adam Kinney has a list with 17 tools that you need to know about when working with Silverlight.
I’ve created my list of favorites tools and libraries and posted them to the Downloads page on the Project Rosetta site. After posting the updated list yesterday I realized I missed two big ones: SilverSprite and Balder.
Breaking the new list down into categories, I ended up with 3 Essential, 4 Optional and 10 Specialty downloads.
