At the time of writing this post, .NET has no specific facility to work with REST services. Though, some services over the web provide information in REST format. For example, http://www.geonames.org (that provides gegraphic information) has a lot of free web services to get geographical information. The other day, I needed to use these services [...]

As I mentioned in the previous post, with Insert, Update and Delete methods but without a Select method, LinqDataSource control looks just like a chair with only three legs! Specially when it comes to situations that you have to retrieve records programatically.

Fortunately .Net 3.5 has a solution for this problem. System.Data.Linq namespace includes a class named CompiledQuery which [...]
