I have been really wanting to spend time on Silverlight lately. I am a real visual learner (and teacher) so Silverlight and SharePoint are a natural fit for me. I want to build up a few posts about the joys and sorrow of getting started. So here goes:
-
Make sure that the post you are reading pertains to your version of Silverlight. I wasted a lot of time on Beta 2 posts while I was troubleshooting. A few things have changed.
-
Make sure you are using an authoritative source for your info, not a hack.
-
Take a methodical approach to building your development environment. I used the Getting Started Video on Silverlight.net.
-
Take baby steps as you build your environment. Just like building SharePoint Web parts, Silverlight has a lot of moving parts. Create the project and build it right away. Test the build and then start ripping through your code. For example, I could not get the simplest empty project to build on my machine. (64 bit Vista). This is my first project:
Graphically rich and compelling, don’t you think? NOT…
So out to the forums and I found this post that implicated the 64bit environment. So I opened up my references and set the System.Web.Silverlight.dll Copy Local property to True. Rebuild the project and everything works as advertised.
Here is the whole error
