Resharper bug reporting issue

I got Resharper 7.1 installed alongside VS2012. After setting up my WP8 project, removing the regular MonoGame reference and adding it through NuGet (3.1.3 -pre), Resharper keeps reporting ‘Cannot resolve symbol’ on all XNA types, even tho the project builds and runs. The only way to solve it seem to unload then reload each project that references MonoGame through NuGet. This has to be done every time the solution is opened. Is there a fix for this?

Installed trial version of Resharper 8 and problem disappeared. Guess ill have to upgrade now.
