Description Emil Sylvest Jensen 2017-01-02 12:18:22 UTC
I accidentally had a property return itself instead of a private variable as I intended (see code below):

public bool IsToggledOn {
            get { return IsToggledOn; } 
}

This made the app crash with no error message and an empty stacktrace when IsToggledOn was accessed, by either the program or the debugger.

Test Application

## Bookkeeping Note

I've attached a console app and Android app that run the code mentioned in the report. 

In the console application, while debugging, I do see a StackOverflow exception is thrown and pauses the debugger. 

While debugging the Android app it simply exits (crashes) without any stack trace information.

I am CONFIRMING this behavior based on https://bugzilla.xamarin.com/show_bug.cgi?id=51167#c1

Although I believe the sample is running into a recursive scenario and this behavior seems reasonable, I am leaving the bug as is until further investigation can happen with the debugger.

This is also happening in VSfMac even for a console project. Assigning to runtime.
