Hi. A few things I noticed while upgrading.
If upgrading an existing project, please note that if you have made any changes to the Site.WithServices.Master view, these will be over-written by the new install - so you will need to merge your changes back from source control.
It did not try to modify Site.WithServices.cshtml.
It deleted the AccountController.cs. I had to add it back in from source control.
Otherwise, all seems good so far. Will keep testing.
Thank you much for the update!
