I get a message saying the following:
Error 1 Package restore is disabled by default. To give consent, open the Visual Studio Options dialog, click on Package Manager node and check 'Allow NuGet to download missing packages during build.' You can also give consent by setting the environment variable 'EnableNuGetPackageRestore' to 'true'.
When I go to Tools -> Options, I do not see Package Manager and underneath I see Package Sources and Recent Packages. I do not see anywhere where I can set Allow Nuget to download missing packages during build though.
