Okay. assume I have structure:

School -> students -> StudentParents <- parents -> address

School can have many students, students can be relatives and have the same set of parents (may-to-many). Each parent can have multiple addresses.
Assume that students who have the same set of parents cannot study in different schools.

If given school_Id =5, I want to remove this school and all related records.
How to do this easily in Entity Framework 4?

    Answer for your question would be same as this question.

    You are trying to solve the problem in the wrong layer. You need to
    reconsider your database design specially how you maintain the
    referential integrity.

    You need to set the “CASCADE DELETE”s of the foreign keys and reflect
    that in your Entity Model. Then the database will make the necessary
    changes to maintain the referential integrity when you delete that
    entity.
