Entity Framework - Insertion to a relational table I am new to Entity Framework and i have to start a application within no time before learning EF in detail. 
I need a help in insertion to a relational table.
Suppose in my application I have two tables Staff and Departments and I have relation table 'StaffDepartment' which has FK constraints StaffID and DeptID. When I generate Models from database , StaffDepartment entity hasnt appeared in the EF. So how can i insert values to StaffDeparment table in EF as i have no dint get any object named 'StaffDepartment'.
Any help will be greatly appreciated. 
Thanks in advance

See walk-through below on generating the model:
EF 4.1 Model & Database First Walkthrough

i would also recommend the follwing guide from microsoft:
http://msdn.microsoft.com/en-gb/library/bb399182.aspx
it shows in a quite simple way how to create/implement and work with a DB in the Entity Framework.
in my eyes you can start with the chapter: "Generating the School .edmx File". but of course it is good to read everything.

Iam sorry for misunderstanding your question! after reading your question again i recongnised that you are looking for something else. But good news! i have exactly what you are looking for:
at first read this:
http://weblogs.asp.net/zeeshanhirani/archive/2008/08/21/many-to-many-mappings-in-entity-framework.aspx
This article explains how to work with "Many to Many" relations.
This article was also very helpful:

it is a little bit easier to undestand because it describes also a way without lambda expressions.
