I've been waiting for a long time to get my hands on a good MVVM library for WinRT. I was excited to hear about Kona, the Prism port for WinRT, and when it came out in beta I snapped it up. I have a WinRT project I've been working on for a while but I didn't want to dedicate too much time to the UI until Kona was released in full. Well, the wait is over!
I was initially shocked and saddened to hear that Kona was dead. WHAT?! Come to find out, "Kona" was just the working name for the project. Once it was solid, the Patterns & Practices group released it as Prism for the Windows Runtime. Evidently they released it last month when I wasn't looking. I'm always last to the party, it seems.
