The dotnet package restore command timed out: "C:\Program Files\dotnet\dotnet.exe" restore "path\to\testproject.csproj"

One of my test projects is now working properly with NCrunch. The only weird thing with this project is that it gives this warning, even though .NET Core is not in the picture:

I'm used to nuget restore and msbuild /t:restore; I'm not familiar with dotnet restore being used on a .NET Framework-only project. So I was surprised, but anyhow.

I think I can see how this would happen. I'll see if I can do some tuning on this.

The rest of my test projects do not build at all with 3.6. All the errors are of the form "The type or namespace name '*' could not be found (are you missing a using directive or an assembly reference?)"
However all the errors point to missing third-party GAC-referenced assembles. They are not NuGet references.

Would it be helpful if I put together a repro for either of these scenarios?

If you could, that would be really great. I'm not sure how MSBuild could fail to resolve a GAC reference. This one has me a bit confused.

Somewhere in the course of fixing the GAC issue and other issues like this one, the dotnet restore warning has disappeared too.

I'll let you know if I can reproduce it again.
