I'm trying to submit an app to the windows phone 7 marketplace and have never encountered this error when validating my .xap package. App Hub just remodeled and became back online roughly an hour ago. Does anyone know how I can fix this?
I'm getting the same thing.. Maybe their new update they just made doesn't work?
Found it... Update Assembly.cs with this:
using System.Resources; // Add this to the top..
[assembly: NeutralResourcesLanguage("en-US", UltimateResourceFallbackLocation.Satellite)]
This worked for me.. Cheers..
Note per Blakomen:
If you are submitting an application for worldwide publishing, you should use NeutralResourcesLanguage("en"), not just "en-US" or it won't show up in the marketplace if you're trying to publish to UK marketplace, for example (it will for some reason come up for Korea and Japan though)
