Unable to See the Model Classes While Adding a New Domain Service

UPDATE

According to a Tweet from Colin Blair you can also add the RiaServices.EntityFramework NuGet package to your project to fix this issue.

The problem

The problem can be recreated by the following:

1. Ensure your have a primary key defined in your table
2. Create a new Silverlight Project, enable RIA services
3. On the server side add a new Data Model then rebuild the solution
4. Click on "Add" -> "New Item" -> "Domain Service class"
5. You see a new "Add Domain Service Class" window but the classes from your model do not show up for use.
   
   
    

The Solution

The Solution is:

1. Open your Model (.edmx file) in Model Designer (just double-click)
2. Right-click in an empty space within the Model Designer & choose "Properties"
3. Change the value of "Code generation strategy" from "None" to "Default"
   
   
    
   
4. Select the Server Project Name (for example MyExample.Web) & click on the "Show All files" button on:
   
   
   
    
5. Expand the "model.edmx" file & locate & delete the 2 .tt files.
   
   
    
6. Rebuild the solution
7. Now click on "Add" -> "New" -> "Domain Service"

Pooff!! This time you will see the classes available in the Add Domain Service Class window.

Hope this helps some poor soul out there like me.
