.RunSynchronously（）和GetAwaiter（）之间的区别.GetResult（）？

Question

I'm trying to run an asynchronous task synchronously and was wondering what the differences between .RunSynchronously() and GetAwaiter().GetResult() were.

I've seen a lot of comparisons between .Wait() and these two methods, but nothing comparing one with the other.

Answer 1

RunSyncronously indicates to run the delegate on the current thread with the current scheduler. However, this applies:

If the target scheduler does not support running this task on the calling thread, the task will be scheduled for execution on the scheduler, and the calling thread will block until the task has completed execution

Wait or GetAwaiter().GetResult() on the other hand doesn't schedule a Task at all, it simply blocks the calling thread until the task completes. This operation can deadlock if called from a single threaded synchronization context.
