Remarks
Scheduler implementations are provided with Task instances to be executed through either the QueueTask method or the TryExecuteTaskInline method. When the scheduler deems it appropriate to run the provided task, TryExecuteTask should be used to do so. TryExecuteTask handles all aspects of executing a task, including action invocation, exception handling, state management, and lifecycle control.
TryExecuteTask must only be used for tasks provided to this scheduler by the .NET Framework infrastructure. It should not be used to execute arbitrary tasks obtained through custom mechanisms.
