Just send a quick email to with a link to this thread. (As always, I'm also happy to reopen the thread upon request within the next month or two. You can submit that test case either via a new bug report or via an email to " Business & Enterprise Support". If anyone continues to see the issue only on Xamarin.iOS after updating to use the candidate fix, the best way forward will be to submit a zipped up test case that demonstrates the problem. The fix is in a debugging library that is shared by both platforms, so in theory it should help with the problem on both Xamarin.Android and Xamarin.iOS. One small caution is that the candidate fix has so far only been tested on Xamarin.Android. I will tentatively close this forum thread to direct further discussion and updates onto a corresponding public bug report that now includes a candidate fix for this issue: Bug 39433.

As of starting yesterday I get the following hickup, when debugging iOS from Visual Studio:
#Xamarin visual studio enterprise 4.0.1.93 update#
I am on the latest Xamarin Update (4.0.1.93).
