I want to use the entity framework to call a stored procedure. I created a function import using the designer in visual studio.  VmwEwonInterfaceEntities is the name of my model and SpCalaculateValues is the name of my sp, so i want to execute this code:

            using (VmwEwonInterfaceEntities entities = new VmwEwonInterfaceEntities())
            {
                 entities.SpCalculateValues()
            }

The problem is that the stored procedure is not available on the model. Did i forgot something?

Urgent please, thanks in advance.

Hi erwin_des;

When you added the class "Linq to SQL Classes" from the Add Item in the Solution Explorer and added the entity class did you drag the stored procedure from Server Explorer to the right panel of the entity designer?

Hi erwin_des;

I have not used this model but will look into this.

It seems that there are some extra stuff to deal with with Entity Data Model in adding a stored procedure. Below is an article showing how to implement a stored procedure with EDM. Look at the section marked "Stored Procedures in the Entity Model"

I hope that this helps.
