问题 Entity Framework Core has yet to implement many-to-many relationships, as tracked in GitHub issue #1368; however, when I follow the navigation examples in that issue or similar answers here at Stack Overflow, my enumeration fails to yield results. I have a many-to-many relationship between Photos and Tags. After implementing the join table, examples show I should be able to: var tags = photo.PhotoTags.Select(p => p.Tag); While that yields no results, I am able to to load via: var tags =
