Silverlight and .NET 4 tools
I've just added two new attributes to SharpToolbox.com: Built for Silverlight and Built for .NET 4.
There are already more than 30 tools tagged as offering support for Silverlight, and 20 tools for .NET 4.
You can search for tools, libraries and add-ins with these attributes using the search page.
PS: if you have submitted tools, be patient, I have a lot to process...
