In my Part 2: Defining our Data Model Classes tutorial I discussed how to use the LINQ to SQL ORM designer to create a LINQ to SQL class model like below:

Figure 3

Notice above how there are two panes on the LINQ to SQL ORM designer surface.  The left pane enables us to define data model classes that map to our database.  The right method pane allows us to optionally map SPROCs (and UDFs) to our LINQ to SQL DataContext object, which we can then use in-place of dynamic SQL to populate the data model objects.
