    out bool isContextSensitive)

Public Shared Function QueryScheduler(
    context As SynchronizationContext,
    isContextSensitive As Boolean) As OpcTaskSchedule.Scheduler

Parameters

Name	Type	Description
context	SynchronizationContext	The SynchronizationContext to post the invocations to, or a null reference (Nothing in Visual Basic).
isContextSensitive	out Boolean	When this method returns, the value true if the returned scheduler posts the invocations to the context; otherwise the value false.
