Hi
I received this exception while I've tried to export to PDF 12 000+ records using Rad ReportViewer; project is made in WCF, version 5.1.11.713, runtime version: v2.0.50727 and I'm not using special code to display/export report/data.
When displaying report no exception raised, only when exporting!
What I discovered is that ReportViewer requires some time to process if this helps...
Exception description:
ContextSwitchDeadlock was detected
Message: The CLR has been unable to transition from COM context 0x458150 to COM context 0x458378 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.
Thanks
Dan
