Problem: I am using the Tutorial.

In the emulator I see a blank form flash up then disappear. When clicking on Debug I get:

Build started... ========== Build: 0 succeeded, 0 failed, 3 up-to-date, 0 skipped ========== The debug was canceled. Please create an android emulator to debug the application.

Did you setup an emulator https://docs.microsoft.com/en-us/xamarin/android/get-started/installation/android-emulator/

[jamesmontemagno]

Or maybe try to run without debugging

[awesomeqed]

The emulator was setup and running. I have since fixed it.

1. I realised that I needed to build the solution and not just the application
2. I also used a different tutorial https://docs.microsoft.com/en-gb/xamarin/get-started/quickstarts/app?pivots=windows I believe that was the issue Thanks for the assistance.
