title: CLR has been unable to transition from COM context 0x3b2d70 to COM context
body: <p>While debugging an application i am getting the following error.</p>
  
  <blockquote>
    <p>The CLR has been unable to transition from COM context 0x3b2d70 to COM
    context 0x3b2ee0 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.</p>
