Error occurred in deployment step 'Add Solution': Sandboxed code execution request failed (but no implementation at all)

Question

I realize of course that there is another question with the same title, and mine is a very similar question, but with a slightly different issue, I think:

I have created an empty feature with an event receiver. I uncommented the FeatureActivated and FeaturedDeactivating methods, but they have no implementation.

When I press F5 to deploy from SharePoint 2010, it builds, but then fails with the error as it appears in the title.

I couldn't find much useful in ULS, and there's nothing in the event log. What gives?

Answer 1

Regardless of what code, or lack thereof, is contained in the solutuion SharePoint will still execute the user/sandobexed soultion inside the sandbox, i.e. it is run but the User Code Service.

I'd take a look at the setup of the User Code Serivce and verify that it is correct, this blog posting may help: http://bramnuyts.wordpress.com/2011/05/17/sandboxed-code-execution-request-failed/

I've also encoutered problems deploying sandboxed solutions from visual studio where they just would not work until they had be been deployed and activated manually once.
