How to call asynchronous method from synchronous method in C#?

Question

I have a public async void Foo() method that I want to call from synchronous method. So far all I have seen from MSDN documentation is calling async methods via

After hours of trying different methods, with more or less success, this is what I ended with. It doesn't end in a deadlock while getting result and it also gets and throws the original exception and not the wrapped one.

private ReturnType RunSync()
{
  var task = Task.Run(async () => await myMethodAsync(agency));
  if (task.IsFaulted && task.Exception != null)
  {
    throw task.Exception;
  }

  return task.Result;
}
