Fixes #18633
Description
In 3.0, we started reverse engineering entity types for tables without a primary key. If the keyless table contained a foreign key, a bi-directional relationship was created for it; however navigation properties to a keyless entity type aren't allowed at runtime.
Customer Impact
The code generated by
dotnet ef dbcontext scaffoldthrows at runtime and needs to be updated manually before it will work.How found
Reported by multiple customers.
Test coverage
Automated tests were added covering the various scenarios reported.
Regression?
No.
Risk
Low. Navigation properties to the keyless entity type are no longer created. An AppContext switch was added to enable reverting to the previous behavior.
