Description info 2012-02-07 07:28:52 UTC
On some devices, and only if no debugger is connected: If there is an outstanding asynchronous WebClient activity, e.g. WebClient.DownloadStringAsync(), and this is cancelled via WebClient.CancelAsync() then the App terminates. The following logging output can be found as the probable reason for the app termination:

02-07 13:25:56.969: E/mono(12646): Unhandled Exception: System.Threading.ThreadInterruptedException: Thread interrupted
02-07 13:25:56.969: E/mono(12646):   at (wrapper managed-to-native) System.Threading.WaitHandle:WaitOne_internal (System.Threading.WaitHandle,intptr,int,bool)

Using Mono for Android 4.0.3. The bug is reproducible on a LG Optimius One, but probably also occurs on other hardware.

Unable to reproduce on our current stable build of Xamarin Android, resolving. Please re-open and provide some sample code or attach a small sample project if you are still seeing this issue.
