Using Stored Procedures

LINQ to SQL allows you to optionally model stored procedures as methods on your DataContext class.  For example, assume we've defined the simple SPROC below to retrieve product information based on a categoryID:

I can use the server explorer within Visual Studio to drag/drop the SPROC onto the LINQ to SQL designer surface in order to add a strongly-typed method that will invoke the SPROC.  If I drop the SPROC on top of the "Product" entity in the designer, the LINQ to SQL designer will declare the SPROC to return an IEnumerable<Product> result:

I can then use either LINQ Query Syntax (which will generate an adhoc SQL query) or alternatively invoke the SPROC method added above to retrieve product entities from the database:
