Today marks the RC1 release of the BindableApplicationBar. I have spent some time today to do some StyleCop and documentation cleanup and it seems ready. You can grab a zip file with the binary directly from here.
Another part of what I have been working on today is a Windows Phone application template. I have spent too many times working on boilerplate code and cleaning up the default Windows Phone Application template and decided to create something that will get me up to speed faster every time I want to create a phone app. It is called Windows Phone Prism Application and is available as a Visual Studio project template here.
