.net core 1.1 web app with Identity Framework “cannot restore…is not compatible with…”

My install of VS 2017 is up to date, and upon creating a new .NET Core 1.1 web app, with Identity (Individual user accounts) I get a slew of errors telling me that packages are incompatible. It would appear to me that something is seriously broken in the tooling for Identity Core. No updates are available. I've tried changing to different "netstandard..." and "netcoreapp..." targets in the .csproj but it doesn't fix it.

If I create a separate project without Identity, it restores and builds as expected.

Here's the full output with my test project:

Try clearing your Nuget cache with dotnet nuget locals --clear all – Travis Boatman
@TravisBoatman Nope, no change after running that. – Tsar Bomba
Like @TravisBoatman said worked for me, clear the NuGet cache and run the web application after – Tassisto
@SamekaTV Did you run it in the context of your web project? I'm not sure if it works if your run it globally. – Travis Boatman
@TravisBoatman I did indeed run it from the app root folder. It obviously ran as expected because all refs were broken in the code, afterward. Restoring packages and attempting to rebuild the solution results in the same error. – Tsar Bomba

Clearing NuGet cache did nothing. Deleting and re-creating the projects made the problem go away.
