Async task not returning value, freezing after compilation. Wpf

Question

I would like to perform (4-5) background Json parsing from web. I've got class with static method:

EventsSingleton.GetPlaces();

Which return list. That's working so far. When I try to async all the operations:

public async Task<List<Places>> Test()
{

    var myTask = Task.Run(() => Test2());
    List<Places> result = await myTask;
    return result;
}


public List<Places> Test2()
{
      List<Places> listatest = EventsSingleton.GetPlaces();
      for (int i = 0; i <= 50; i++)
    {
        progressBar5.Dispatcher.Invoke(() => progressBar5.Value = i, DispatcherPriority.Background);
    }
    return listatest;
}

Everything is still ok by now, correctly returning list and setting progressbar. Problem came out when I tried to return that value to my page contructor (or to OnClickButton method). I'm trying to do:

 var list5 = Test().Result;

But after compilation my program doesn't even start. I thing that my list isn't prepared yet, but maybe that "await" should do the job?
