It appears when the AppBuilder extension is enabled, you're unable to execute the command "Enable-Migrations" to enable code first Entity Framework migrations. Doing so causes this error to be returned:

Disabling the AppBuilder Extensions allows the command to execute properly. Is this a known issue, is there a fix?
