The problem is that dotnet build fails (see https://github.com/dotnet/cli/issues/8187). So other tools like the Entity Framework ones that return the contexts in the project don’t run. This is also why Apply Migrations checkbox does not appear in Visual Studio Web Publish Settings.
Yep, same problem. Fixed build and problem went away.
