Task::RunSynchronously Method (TaskScheduler)
Assembly: mscorlib (in mscorlib.dll)
The Task instance has been disposed.
The scheduler parameter is nullptr.
The Task is not in a valid state to be started. It may have already been started, executed, or canceled, or it may have been created in a manner that doesn't support direct scheduling.
A task may only be started and run only once. Any attempts to schedule a task a second time will result in an exception.
If the target scheduler does not support running this task on the current thread, the task will be scheduled for execution on the scheduler, and the current thread will block until the task has completed execution.
