Restore Incompatible Runtime Error

[wjk]

I am trying to run dotnet restore on a fairly simple project of mine (private repo); however, I get the following errors:

I have tried explicitly specified the runtime (dotnet restore --runtime win7-x64), but to no effect. Any idea what is going on?

Weirdly, dotnet compile succeeds with no errors when run on the same project.

try adding Microsoft.NETCore.Platforms: 1.0.1-rc3-23729

and then calling dotnet build

That did it, all right. Thanks!
