A Custom ASP.NET Silverlight 5.0 RIA Services DomainService with Dapper-Dot-Net

A Custom ASP.NET Silverlight 5.0 RIA Services DomainService with Dapper-Dot-Net Silverlight RIA Services has undergone steady improvements, and it is included With Silverlight 5.0.

You add methods to your all the columns in the Northwind Employees table in this class. When you create your Silverlight Solution, remember to check the box "Enable RIA Services". I'll be using a DataGrid with a DomainDataSource control, which is preconfigured to be able to work with a DomainService
