[Solved] How do I submit my game to the Xbox device family?

Just sharing another tip I didn't know for a couple of months: To target the Xbox device family, you need to first right-click the project name at the right in Visual Studio, and select Properties, and change both the Target version and Min version to 10.0.14393.0.

Thanks for posting this tip. I've been tearing my hair out trying to figure out why the Xbox device family wasn't available.
