I am getting an error when trying to enable package restore in a new solution I just created. The error in VS2012 is:
NuGet Package Manager
An error occurred while configuring the solution to restore NuGet
packages on build
Unable to read package from path 'NuGet.Build.2.7.0.npkg'.
I tried opening the solution in VS2010 to work around the problem and I am also getting an error when trying to enable package restore, but the message is different:
NuGet Package Manager
An error occurred while configuring the solution to restore NuGet
packages on build
Archive file cannot be size 0.
I tried creating a new solution, but got the same result.
I then tried doing a repair on VS2012 update 3 and rebooting. Still getting the problem.
I also scanned the folder, project, and solution file for anything NuGet or .nupkg, but there is nothing there.
So how can I get this feature working again? The last time I used it was about a week ago, and I don't remember specifically what I changed since then. I uninstalled the VS Power Tools package that I installed about a week ago, but that didn't fix the problem either.
Update
I followed the "removal" instructions here and used a project I already have as a template to enable package restore manually. However, I am still looking for a better solution because this is a feature I use frequently.
I also tried uninstalling and reinstalling NuGet from visual studio, but I still get the same issue. If memory serves correctly, there was a recent NuGet update (is there a log for VS extension installation so I can check?).
