I have a class in which constructor I need to use one async method. The problem is that in a constructor I can use the async keyword so I can't use the await with async method. So by the moment I am using this way:

Task myTask = Task.Run(() =>
                {
                    myList.AddRange(MymethodAsync().Result.OrderBy(x => x.Name));
                });

But I don't know if it is the best way, wrap the method in a task.

I have tried this:

myList.AddRange(MymethodAsync().Result.OrderBy(x => x.Name));

But this block my application, it is a problem with Result.

Really I need to use in the constructor various async methods, that if I could, I would like to run in parallel and wait until all of them have finished.

Thanks.

Constructors, as their name suggest, should be used only for initialization logic. Async calls belong to methods. – Darin Dimitrov Apr 23 '17 at 07:39

I don't call the constructor in the async method, at contrary, I am trying to call the asyn method in the constructor of my viewmodel. – Álvaro García Apr 23 '17 at 07:55
Yes, and this is what you shouldn't do – VMAtm Apr 23 '17 at 16:07
