CallbackToAsync
//For example, given the following method:
public void GetStringFromUrl(string url, Action<string> onCompleted);
//The only way I know of to wrap this into a method returning a task is:
public Task<string> GetStringFromUrl(string url)
{
var t = new TaskCompletionSource<string>();
GetStringFromUrl(url, s => t.TrySetResult(s));
return t.Task;
}
