Define relationship many to many in Entity Framework using Fluent API

Question

I want to create the folllowing link table using fluent API.

HasMany(u => u.VehicleGroups).WithMany().Map(m =>
            {
                m.MapLeftKey("RoleId");
                m.MapRightKey("VehicleGroupId");
                m.ToTable("RolesVehicle");
            });

Is it possible to add the field Id to table RolesVehicle which will be my primary key?

Answer 1

是的，但是只能通过创建单独的实体RolesVehicle ，该实体具有您的Roles和Vehicles实体以及所需的任何其他字段的键和导航属性。
