Screenshot of the error
I'm facing a bug while debugging an ios application with Visual Studio.
After a few play with the application with the debugger connected, I have an error message in visual studio (see in attachement).
It seems to happen when a new thread is running with a number already used before (thread #10 in the example below).
I'm using the Google maps component in my project, so the map tiles fetching system must be the one which generate so uch threads.
When using the application without the debugger attached, I have no problems. But it's impossible to debug, because the problem appear whithin some seconds after the application launch.
Here's an extract from the output window :

Additional information may be available in bug https://bugzilla.xamarin.com/show_bug.cgi?id=32361
I closed that one as a duplicate of this.
This has now been fixed in master and will be available in the next alpha refresh.
I have tried to verify this issue with latest C6 builds, but getting another issue while the running the app with this builds, so I have Reported another Bug 34711 for the same.
