Using windbg to identify the code a System.Action will execute

Question

Something went horribly wrong with my WPF application and it appears I have 24 million actions on the dispatcher waiting to run.

windbg with sosex shows me

0:000> !dumpgen 2 -stat
       Count      Total Size      Type
-------------------------------------------------
...
      23,967,120    575,210,880   Catel.MVVM.Command`2+<>c__DisplayClass35_0[[System.Object, mscorlib],[System.Object, mscorlib]]
      23,967,139    575,211,336   System.Windows.Threading.DispatcherOperationTaskSource`1[[System.Object, mscorlib]]
      23,967,139    575,211,336   System.Windows.Threading.DispatcherOperationTaskMapping   
      23,967,139    575,211,336   System.Threading.Tasks.TaskCompletionSource`1[[System.Object, mscorlib]]
      23,967,139    958,685,560   MS.Internal.CulturePreservingExecutionContext
      23,967,120  1,533,895,680   System.Func`1[[System.Threading.Tasks.Task, mscorlib]]
      23,967,139  1,533,896,896   System.Windows.Threading.PriorityItem`1[[System.Windows.Threading.DispatcherOperation, WindowsBase]]
      23,967,554  1,533,923,456   System.Action
      23,967,139  1,917,371,120   System.Threading.Tasks.Task`1[[System.Object, mscorlib]]
      23,967,156  2,109,109,728   System.Threading.ExecutionContext
      23,967,139  2,684,319,568   System.Windows.Threading.DispatcherOperation

Is there a way I can see the actual code that the Action will be executing? I have a rough idea what is going on based on the objects reference by the above, but seeing the actual code the Action will execute will be helpful.

Please post the output of `!sosex.mdt` or `!sos.dumpobj` for one of them. You need to look at the _invocationList property to see what objects are in there. From there, proceed to dump, using `mdt` or `dumpobj` the contents. — Steve Johnson, Dec 14 '16 at 21:46

Can you confirm that yours in x64 (from the memory consumption it looks like). Look at the related question and please tell us why this is not a duplicate. — Thomas Weller, Dec 19 '16 at 11:58
