More code snippets and samples around the web for developers this morning, which is great news. The last thing that coders want to be is the only person working on a platform, so a flow of others showing what they're up to - and more importantly how they are doing it - is a great sign in the ecosystem. Matthias Shapiro's blog covers Silverlight and WPF, and today looks at how to have your Windows Phone app log in to Facebook so you can do... social things.

He takes you through the working of a dummy Facebook application (called UnNamed Nonsense Tutorial), setting up Facebook's social graph API, the SDK additions, and then the code to have the user of the Windows Phone app do the actual logging in.

A more detailed explanation is thankfully available in a zip file on Shapiro's blog, as is sample code.
