How to fix restoring nuget packages error?

After a couple of weeks I revisited my .NET C# project in Visual Studio 2010. I changed just one line in source code and tried to rebuild the project and I get this error:

Error occurred while restoring NuGet packages: could not be found. (Exception from HRESULT: 0x80030002 (STG_E_FILENOTFOUND))

I don't have the slightest clue why this error appeared. Nothing was changed, somehow this nuget got corrupted. I have done a lot of searching via google but found nothing that would get me on the right track.

is it possible to remove nuget all together, because it is nothing but a cause of grief?

I've faced with the same issue: I solved this problem by going to Tools -> Options -> Projects and Solutions -> Build and Run and clicking on OK

I also had this call stack:

    System.Runtime.InteropServices.COMException (0x80020009): Exception occurred. (Exception from HRESULT: 0x80020009 (DISP_E_EXCEPTION))
