Unexpected Error on Capability Validation when running Marketplace Test Kit of Windows Phone

Question

I'm trying to submit an update of my application and the Capability Validation test of the Marketplace Test Kit is returning "[ERROR]: Unexpected Error". What a great error message.

Submitting the update to the marketplace also gives me the same error.

Any ideas?

Answer 1

The required capability sections are fine into to the App Manifest file. I tried everything.

In the end, I created a new empty project, copied all files to it and voilà: everything worked.

I will never understand why...
