The Entity Framework together with LINQ to Entities are very powerful technologies to access and manipulate data from a database. At first glance everyone is impressed by the conceptual layer which is mapped to tables in a database. When building large scale enterprise applications you will notice that the EF has a few shortcomings. When you need to gain performance or need extra security, stored procedures and user defined functions are often required. In this first article in a series of three I will focus on how to use stored procedures in the Entity Framework 4.0. In the second article I will demonstrate how to map user defined functions to model defined functions and to call them in LINQ to Entities queries. And in the final article SqlClr functions will be explored.
