This is the closest place to Windows Phone 8 I can get. Sorry if it is not the right place.
I have found a bug in the WP 8 runtime that crashes the app when a type is not found in a assembly namespace that is identified as Strong Named. Basically, if you use the Type.GetType() method to locate a type that does not exist in the assembly (and that assembly path in your string is marked with a PublicKeyToken value), then the runtime will crash instead of letting you handle the System.IO.FileLoadException. I have found this to be the case *only* in the emulator so far.
