Entity Framework subquery

Question

Guys I am new to Entity Framework and I\'m having a bt of a problem that I have been trying to solve for quite a while. Basically I have 4 entities: users, groups, books an

Answer 1

Personally I think there is a better solution(untested of course):

First select from ReadList by GroupdID, then join in books on BookID.

IQueryable q = 
       from rl in entities.ReadingList
       join b in entities.Books on rl.BookID equals b.BookID
       where rl.GroupdID ==groupID
       select b;

var books = q.ToList()

Please let me know if you have any issues.
