ooh i see.. my understanding is if we call without async it will become synchronus..

what If I use the following?

Task.Run(async () => await Run_ForgetIt(new object[] { }));

await is a compiler feature that converts the code following the await into a callback executed when the async routine completes. in:

Task.Run(async () => await Run_ForgetIt(new object[] { }));

as you are not awaiting the result, there is no need for async or await, just:

Task.Run(() => Run_ForgetIt(new object[] { }));

this is how you fire and forget a sync routine. if you did not trust that Run_ForgetIt is truly async, then this would force it. but in general creating a new thread is not required to call an async routine.

Run_ForgetIt(new object[] { })); // if async, fire and forget;
