Answer 1

Have you imported your stored procedures in the EF model correctly? and are you setting correct return type to stored procedures??

There are 4 possible return type that you can set to your procedures The possible return types are:

1. none
2. Scalars
3. Complex
4. Entities

you need to set scalars return type.

if you dont know how to set the return type, then here is the full tutorial http://www.binaryintellect.net/articles/30738a7c-5176-4333-aa83-98eab8548da5.aspx

quick example.

CREATE PROCEDURE CustOrderCount
    @CustomerID nchar(5)
AS
BEGIN
    SELECT COUNT(*) FROM ORDERS 
        WHERE CUSTOMERID=@CustomerID;
END


NorthwindEntities db = new NorthwindEntities();
var count = db.CustOrderCount("ALFKI");
int ordercount = count.SingleOrDefault().Value;

this will return int order count.
