In the following it is used the AdventureWorks DB on SQL Server 2008.
Add a new Stored Procedure from the DB to the Entity Framework via Update Model:
In the case I added the following usp:
EF has two parts, the DB-side (where we added the Stored Proc) and the object-side where we will create the needed classes now.
A double click on the new Stored Proc above (or right click, Add Function Import) opens the dialog Add Function Import below.
Click the first button (A:) to get the output column info from the SP, then the second button (B:) to create a new complex type, based on this info, then OK
This creates the complex type and C#-Function on the EF4-object-side:
Calling the SP through EF is accomplished like so:
Observe the datatype of the list p
Here comes the result of the first entry of p:
Compare this with the result of calling directly the SP in SSMS:
