Project Template for an MMVM Light Universal App
This here is the basis of a Visual Studio project template that will create the skeleton of an app that looks and feels a lot like the built in Microsoft Windows 10 app (Weather, NFL etc). It's got all the basic stuff plumbed out like navigation and a navigation control, a settings page, Theme switcher etc. The Wiki has some more detailed description of how things work (kind of a work in progress).
There is a Visual Studio extensibility package up on the community site.
If you use MVVM Light the resulting project code will look pretty familiar, and there are some TODO comments to show where to plug in the specifics for your app. If you start with the Code from this repository replace all instances of the string "SKELETON" with your app's root namespace. However, starting from the code in this repository is not recomended as the you won't get the autogenerated package family name in your app manifest (though you can update manualy in the Xml file).
