Now that you've made things clear, the questions you ask make more sense to me. The thing is that we analyze the generated file, because any types declared within it might be used throughout your silverlight application. Still we do not navigate to the file on double-click in the error window, because the file itself is not a part of the solution. If you include it, though, you'll be able to navigate correctly.
Out of curiosity, how do you get an error in the generated file anyway? AFAIK, the file is generated only when the original is successfully compiled, so that no errors will be introduced in the generated file. You could've introduced these manually, but the generated file will be overwritten, once you compile your solution again. So, what's the trick there?
Anyway, we should definitely give some more thought on the behavior of JustCode, concerning these generated files. Thanks for the involvement.
All the best,
the Telerik team
