How to call async method in sync method in .net core

Question

I found some ways to call an async method on a sync method, but I don't know what is the best way in .net core and why?

DebugLog.Log(ex.ToString()).GetAwaiter();
System.Threading.Tasks.Task.Run(async () => await DebugLog.Log(ex.ToString()));
DebugLog.Log(ex.ToString()).RunSynchronously();
DebugLog.Log(ex.ToString()).ConfigureAwait(default);

There is no best way. If there was, then everyone would just use that.

There are a variety of approaches, each with their own drawbacks. The two most common are:

GetAwaiter().GetResult() (i.e., direct blocking) - can deadlock.
Task.Run(...).GetAwaiter().GetResult() (i.e., block a thread pool thread) - doesn't work if the ... requires the current context.

RunSynchronously should never be used.
