2Breaking on the debugger doesn't show where it's at that point? – Sami Kuhmonen Apr 13 '16 at 10:18

logging a.k.a. `Debug.Write` is your friend. riddle your code with logs and read the logs – Thomas Andreè Wang Apr 13 '16 at 10:36

Is there is any tool is available to find the dead lock? – Farjana Parveen Ayubb Apr 13 '16 at 10:49

Is the deadlock reproducible ? Have you tried simplifying your app (removing user controls / commenting out method calls etc) to narrow things down ? You need to have a general idea on when / how the hang occurs and take it from there. If you're completely stuck then roll up your sleeves and use windbg / sos - but that's not the easiest tool to use - see [msdn](https://msdn.microsoft.com/en-us/library/bb190764.aspx) – auburg Apr 13 '16 at 10:59

If you have a simple deadlock, pause execution in the debugger and inspect every thread. – yaakov Apr 17 '16 at 06:32

First of all you check if there is an exception which is thrown on background. In order to turn on the CLR exception to be thrown go Debug/Exception and check the Common Language Runtime Exception check-box. Secondly you can try to pause a debugging session, and try to see where is each thread at the time that the application was dead-locked and research the Callstack. In addition you can trace each place that probably can be a cause to dead-lock.
Here is some SO query that can help you:
Here are some tool that in my opinion can be useful in this case:
- OzCode - can help you to debug and manage situation in a better way(allows to trace the code in a better way and more...).
