This is an interesting development which demonstrates the essentials of  how a LINQ provider can be built for connecting to Twitter API using LINQ framework.

I had been working on Linq since 6 months the concept is awesome. I am big fan of LINQ and Twitter is the Social Networking platform I use and anything coupling them would be really intresting. I have thought of creating providers for databases but creating a provide for Public API was I never thought of.

This is what the lead, JoeMayo,  says there

So far, LINQ to Twitter demonstrates the essentials of how a LINQ provider can be built and supports a couple simple queries, such as Public and Friends. You’ll begin to see more features in time, focusing on sub-sets of the Twitter API. In the next release, I’m planning on finishing infrastructure tasks and adding support for all of the optional Friends parameters.  More later…

This project is still in beta and If anybody wants to join in the development you can head towards Linq to Twitter @ Codeplex
