Cannot use table 'VorgangVorgangNachricht' for entity type 'VorgangVorgangNachricht (Dictionary<string, object>)' since it is being used for entity type 'VorgangVorgangNachricht' and potentially other entity types, but there is no linking relationship. Add a foreign key to 'VorgangVorgangNachricht (Dictionary<string, object>)' on the primary key properties and pointing to the primary key on another entity typed mapped to 'VorgangVorgangNachricht'.

OK, I fixed it by writing this configuration inside Vorgang:

// EF Core 5 many-to-many
            entity.HasMany(e => e.Nachrichten)
                .WithMany(e => e.Vorgang)
                .UsingEntity<VorgangVorgangNachricht>(
                    vvn => vvn
                        .HasOne(vvn => vvn.VorgangNachricht)
                        .WithMany()
                        .HasForeignKey(x => x.VorgangNachrichtId)
                        .HasConstraintName("FK_VorgangNachrichtId"),
                    vvn => vvn
                        .HasOne(vvn => vvn.Vorgang)
                        .WithMany()
                        .HasForeignKey(x => x.VorgangId)
                        .HasConstraintName("FK_Vorgang_VorgangId"));

Configuration inside VorgangVorgangNachricht from my first post is deleted

But this error is really confusing... And it didn't say nothing about trying new EF Core many-to-many configuration

@Saibamen If you post a repro project that generates that error, then we will take a look.
