Done. We've published 1.1.0-beta-000001 packages to NuGet that take dependencies on 1.1.0 packages rather than 1.0.1 ones. The source for this is in the netcore-1-1-update branch that will be merged to dev once we're ready to move on from 1.0.1 completely.

Is this available via the yeoman generator at all? If so how would I install it?
