How do I use a custom build of the Silverlight Toolkit to build my Silverlight project? I'd like to be able to step into Toolkit code while debugging.
Go to the SourceCode tab and get the latest build for Toolkit.But you will have to reference Toolkit Project in you Working project to be able step into toolkit code while debug .
Here you can find latest builds list: http://silverlight.codeplex.com/SourceControl/list/changesets
