I solved this by removing the Design reference and only using the tools reference.

edit:

Over time gave me another error, from what I can tell the problem is that Microsoft updated their design package but not their tool package, so both don't work together, since if you follow their tutorial it should get the latest package you get an error by following it.

I solved it by forcing both packages to the 1.0.0-preview2-final. My updated project.json:

  "buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true
  },
