NuGet Package restore failed for project Miscellaneous Files: Value cannot be null or an empty string.in VS2013

Question

I keep getting this error in VS2013. I checked this SO post on it and other search links and they say to upgrade to NuGet 2.8 which fixed this error of 2.7. I have and I keep getting this error. FWIW, its on a Unit Test project. It has something to do with the XUnit package because I get this error when I am using that package.

Solution

Just download NuGet 2.8+

They solved this problem, It's from their side.

Thanks
