Reading this today, and probably embarking on a Xamarin solution very soon (the other possibility is "going native" with just Android, using Android Studio), I got to wondering:
Can ELMAH be used in Xamarin solutions?
And, in fact, if the road less taken (Android Studio) is chosen, what tool is there for Android/Java projects that that most closely resembles ELMAH's advantages?
No. ELMAH is very specifically targeted for ASP.NET.
Error/crash logging solutions for Xamarin include Raygun, Crashlytics, and TestFlight.
