I just downloaded MonoGame 3.7.1 and I'm using Visual Studio 2017 Enterprise.
When I create a new project of type "MonoGame Android Project", it doesn't build because "AndroidManifest file does not exist." So, I right-click on the project, go to Properties > Android Manifest > create AndroidManifest.xml.
The project now builds; however, my Android emulators are not listed in the Start dropdown.
On the other hand, when I create a new Xamarin.Android project, and all of my devices are listed.
I've tried tinkering with the AndroidManifest, but I haven't had any luck. Any ideas?
