I have such error in vs 2012: NuGet Package restore failed for project Miscellaneous Files: Value cannot be null or an empty string. Parameter name: root. 0 0

I see that it's a bug https://nuget.codeplex.com/workitem/3780 that was fixed for version 2.8 But I can't find the 2.8 version on https://nuget.codeplex.com Is it possible to fix the error without the installation of the 2.8 version? Or how to get the 2.8?

I fixed this issue after clicking the "Clear All Nuget Cache(s)"

Nuget Tools -> Clear All Cache

None of the above answers helped for me, and it was getting pretty frustrating.

What worked for me (with Visual Studio Professional 2017, version 15.8.5) was doing the following steps;

1) Tools > Options > NuGet Package Manager > Click 'Clear All NuGet Cache(s)'

Hope this helps someone!
