多对多表首先与EF6数据库映射为一个实体

Question

I have an Issue with Many-to-Many mapping. I have the following tables created on MySql database:

In edmx I tried to map it with Update Model From Database:

But when the tables are mapped, the table Many-to-Many usuarios_conquistas is mapped as an Entity (not only a relationship between tables usuarios and conquistas ):

Anyone knows what I'm doing wrong?

Answer 1

“ usuario_conquistas”表不应具有列ID，而应使用列IdUsuario和IdConquista作为组合主键。
