Also in our Silverlight application, intermittently, we see the same NullReferenceException in XapModuleTypeLoader.GetParts() which the OP reported. This is an in-browser application, when deployed: I've not seen this problem in a development environment.
Note that we don't see a NotFound error being reported-- but I have no network or HTTP trace of this error situation, so I don't know whether or not an HTTP error is sent back from the server.
In the one instance I've seen, this exception probably occurred the first time the Silverlight page was loaded after installing the application. And it seems to occur for each of the (many) .xap files in our application.
Any light?
Thanks!
