Hi
I am getting below error on a long running query crashing the app, even though I am running the query as background task;
ContextSwitchDeadlock was detected
Message: The CLR has been unable to transition from COM context 0x623978 to COM context 0x623ae8 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.
The code is below. How can I fix the 'ContextSwitchDeadlock was detected' issue please?
Function ExecuteSQL(ByVal St As String) As Boolean
Try
Try
Dim result = ExecuteSQLAsync(DBCommand)
I = result.Result
Catch ae As AggregateException
For Each ex In ae.InnerExceptions
Throw
Next
End Try
Return True
Catch ex As SystemException
MsgBox(ex.Message)
Return True
End Try
End Function
Async Function ExecuteSQLAsync(DBCommand As SqlCommand) As Task(Of Integer)
Dim x = Await DBCommand.ExecuteNonQueryAsync()
Return x
End Function
Thanks
Regards
