Like Keith Barrows, each time I see a message like below, I’m reminded that I forgot to change my Visual Studio 2005/2008/2010 to disable these kinds of MDA messages:
ContextSwitchDeadlock was detected Message: The CLR has been unable to transition from COM context 0x1a7728 to COM context 0x1a75b8 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.
Steps to get rid of these messages:
- Start Visual Studio :-)
- In the menu, select “Debug”; “Exceptions…” (Ctrl-D, E)
- Open the “Managed Debugging Assistants” tree
- Uncheck the first checkbox in the “ContextSwitchDeadlock” row
Maybe I won’t forget this next time :>
