Recently, I did couple of posts regarding how to create a custom LINQ provider, I even created a project at Codeplex named LINQ.Flickr, that makes querying , adding and deleting photos , overall creating Flickr app much more enjoyable , with query flavor, similar to LINQ to SQL.
So , I tried to sum it all up in a article named LINQ provider Basics. Those who want to see how it is going, I definitely suggest to have a look.
Although , there is a simple web app implemented with my LINQ provider that can be downloaded from LINQ.Flickr project. But in coming posts , I will definitely try to write how to make one easily with the provider.
