Description Manish Sinha 2017-08-22 17:26:31 UTC
Steps to reproduce

1. Create a Cocoa App in VSMac
2. After ViewDidLoad, add the following lines

> var backgroundQueue = new DispatchQueue("nameOfDispatchQueue", false);
> backgroundQueue.DispatchAsync(() => throw new Exception("Exception in background queue"));


Expected: Since the dispatched delegate hits an exception, the IDE should notify the user of an unhandled exception
Actual: No exception dialog shows up and the only error shown is in Application Output, only if Continue button is pressed
