Visual Studio Won't Deploy Project On Android Emulator

Question

I just installed VS2017 and created a vanilla project just to see if I can get it to run on the Android emulator. The project builds, the emulator starts and runs but my application does not start in the emulator. I get no errors when the project is built or deployed. Can you please give me an idea as to where I can start to troubleshoot this.

This is what the emulator looks like and it just sits there instead of showing the application built/deployed above.

Answer 1

In the "Configuration Properties" of the main solution file check that the "Deploy feature" is enabled.

Answer 2

I have the same issue with Avalonia Cross Platform on VS22, The solution is very simple

1. open The Configuration Manager
