Should it be possible to create a connection with a .dll that references EF Core 5.0?

The Test connection feature fails with error after compiling a .dll that references EF Core 5.0 Preview 3. I am still able to execute queries against the source, but the Context does not populate the Entity tree in the left hand connection pane of LinqPad.

The error I am receiving is:
Error Testing EF Core Connection: Method not found: 'Microsoft.EntityFrameworkCore.Metadata.IEntityType Microsoft.EntityFrameworkCore.Metadata.INavigation.get_DeclaringEntityType()

  • They've moved the DeclaringEntityType property into a different interface, breaking binary compatibility. I'll include a fix in today's beta (6.8.3) that will use dynamic binding to work around the issue. Let me know how you get along.
