* Switch from using the embedded file provider for the precompiled views
for actual razor precompilation.
* Add MSBuild props and targets file to include additional assembly
attributes on the generated precompiled views.
* The default UI uses its own Area (Identity).
* The default UI requires MVC and StaticFiles to be present on the
request processing pipeline.
* The default UI requires the user to provide a '_LoginPartial ' partial
view in their application in a location that the view engine will find
it. This location is tipically /Pages/Shared or /Views/Shared
* Current limitations:
* The UI is self-contained and non-customizable (outside of things possible with Razor pages).
* Customizing the User, role, etc. is not supported at this time.
