@Peter Forstmeier , there aren't any plans to update the Azure Mobile Apps SDK. I suggest reviewing this blog post, which contains a link to the repo where you can submit feedback as well as some sample apps. You may find developer mobile apps doc helpful. Unfortunately, though, you won't find much on offline syncing.
EDIT: Please check out https://github.com/Azure/azure-mobile-apps-net-client/blob/master/CHANGELOG.md for the latest changes to the Azure Mobile Apps SDK. Do note any breaking changes listed to ensure no negative impacts to your application.
