DisconnectedContext was detected
Message: Context 0x3eb6e0' is disconnected.  Releasing the interfaces from the current context (context 0x3eb570).This may cause corruption or data loss. To avoid this problem, please ensure that all contexts/apartments stay alive until the applicationis completely done with the RuntimeCallableWrappers that represent COM components that liveinside them.


ContextSwitchDeadlock was detected
Message: The CLR has been unable to transition from COM context 0x3eb570 to COM context 0x3eb6e0 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.
