It’s interesting I am seeing more and more silverlight applications being added to CRM and it makes me want finish studying my 70-515 exam quicker so I can start playing around with Silverlight myself.
which reminds there is a good interview with David Yack here
David has a couple of books out soon on Silverlight, I read a couple of the early chapters and they should be good.

Anyway back to the topic, one of my favourite bloggers MSCRM blogger has recently created a silverlight project to allow you to attach features onto an entity in CRM. You can read the original blog post here, I would also recommend reading other blog posts because although he isn’t a prolific blogger the quality of the blog posts are worth waiting for.
You can see the project on codeplex here
