This Friday, June 25th, marks the start of CodeStock 2010: The Year We Connect. According to the CodeStock website, the theme for this year is about establishing connections.

Read the other posts in this series: Part I Part II In the previous blog posts listed above, I showed how Telerik’s new LINQ implementation works with WCF RIA Services.

In my last blog post, I showed how Telerik’s new LINQ implementation works with WCF RIA Services. In that post I built a Domain Model from the Northwind database as well as a RIA Services Domain Service. I then showed the drag and drop features of RIA Services and created a simple Silverlight application with no code. Today we are going to take that example one step further by creating some custom server side Query Methods. A query method is just a facility to query a data source. In RIA Services, you define a query method explicitly so it can be used on the client. This is pretty straight forward...
