Entity Framework include with left join is this possible?

Question

I have the following tables

1. ClassRoom (ClassID,ClassName)
2. StudentClass (StudentID,ClassID)
3. Student (StudentID,StudentName,Etc..)

Answer 1

Exactly:

1. If StudentDescription.StudentId is nullable -> EF performs a LEFT JOIN, i.e. select * from Student s LEFT JOIN StudentDescription sd on s.StudentID=sd.StudentID.
2. Otherwise EF does INNER JOIN.
