CLR cannot convert from com context 0x208f68 to com context 0x2090d8, which has lasted 60 seconds. The thread with the target Context/unit is likely to execute a non-pump wait or process a very long operation without sending a Windows message. This usually affects the performance, and may even cause the application to not respond or the memory used to accumulate over time. To avoid this problem, all single thread unit (STA) threads should use pump-type wait elements (such as cowaitformultiplehandles ), the system periodically sends messages during a long running period. When the network speed card is used, the system prompts this exception.
