Debug Signing in Visual Studio 2017 Preview

I know this isn't maintained any longer, but it might help someone who is having a similar issue to me in the future.
If I build this project in VS 2015/2017 it honours the signing settings in the project file, in my case c:\Users\dev.android\debug.keystore, which is great, and auth works perfectly.
I decided to test this in the new Preview release of VS 2017 15.4.0 Preview 2, and it has the strangest behaviour. The compiler will switch randomly at build time between my debug.keystore, the project debug.keystore, and the default Xamarin debug.keystore. I only noticed because I was bored and watching the compiler this morning.

Executing: C:\Program Files\Java\jdk1.8.0_121\bin\jarsigner.exe -keystore "C:\Users\dev\AppData\Local\Xamarin\Mono for Android\debug.keystore" -storepass android -keypass android -digestalg SHA1 -sigalg md5withRSA -signedjar "C:\Users\dev\AppData\Local\Temp\5i2m1e0q.tki\unaligned.jar" "C:\Users\dev\AppData\Local\Temp\5i2m1e0q.tki\unsigned.apk" androiddebugkey

I only mention this because I did not know that Xamarin had it's own debug.keystore, there is no way this is listed in the projects settings anywhere. It's something to be wary of when you are putting your store fingerprints in Firebase.

Thanks

Closing as it's not an issue.
