EF 6 Code First From Database - Calling existing stored procedure

You need to define a DTO for each stored procedure. You just create simple classes where the propery names of the classes match the name of the columns that are returned by the stored procedure. So, when you call the Stored Procedure from EF, your objects are built and populated. The performance is great! Here I'm pasting an example:

dbContext.Database.CommandTimeout = 3600;
List<CarsDTO> objs = dbContext.Database.SqlQuery<CarsDTO>(
         "spGetCars @carMakeId", new SqlParameter("carMakeId", id)
).ToList();
