EF Core compiled model is broken for EF8 RC1

[olegsavelos]

I am getting this error when trying to create a compiled model (dotnet ef dbcontext optimize).

System.InvalidOperationException: The type mapping used is incompatible with a compiled model. The mapping type must have a 'public static readonly SqliteGuidTypeMapping SqliteGuidTypeMapping.Default' property.

This issue is lacking enough information for us to be able to fully understand what is happening. Please attach a small, runnable project or post a small, runnable code listing that reproduces what you are seeing so that we can investigate.

There is nothing special required, at least in my case. Just adding any entities to context and trying to create compiled model.
I have attached an simple project that can be used to replicate this (at least on my machine :))

Note for triage: still fails with the latest daily build and looks to be SQLite-specific.
