10 months ago Same issue here - I think the table names are now correct but Foreign Key names have changed.
EF migrations now just die with the above error

10 months ago I'm seeing the same issue, and I made a short repro showing my scenario failing with 8.0.x.
In my case it seems to concern a one-to-one relationship where I define the principal entity first, including a nav property for the secondary entity. Then in the second entity, I define the relationship.
This used to work regardless of order, but now requires specific ordering.
Expected error in repro: Host can't be null
Actual error: The object has been removed from the model
Repro with top-level statements: Project.csproj

}
public class DummyPrincipal
{
public long Id { get; set; }
public DummyOther Other { get; set; } = default!;
}
public class DummyOther
{
public long Id { get; set; }
public long PrincipalId { get; set; }
public DummyPrincipal Principal { get; set; } = default!;
}Looking through the commit log there seem to have been a number of fairly significant code changes since rc2 - I think an rc3 would have been justified.

10 months ago This was introduced in #244. I've pushed a fix and will release 8.0.2 momentarily.
Hello, I am using UseSnakeCaseNamingConvention with postgress. After migrating from version 8.0.0-rc.2 to 8.0.0 or 8.0.1 I am getting the error below when I am trying to access dbContext. I am not sure what could cause this issue.
