Are you a developer looking to build a Silverlight application using the New York Times API? Well, now you can. The New York Times Silverlight Kit has just become an Open Source project distributed under the MS-PL license. If you’re not familiar with what this kit does, it’s something that you can add into a Visual Studio or Expression Blend Silverlight 2 project to get easy access to the New York Times APIs for Articles, Best Sellers (books), the US Congress, Movie Reviews, Community Comments, Times Tags, and more. You can check out a demo of the kit here or see an application built using the kit here. The app is called “Artist Explorer” and it lets you research musicians using the NY Times API as well as Billboard and Best Buy.
