        await Task.Run(async () =>
        {
            // Some code that can throw an exception
            ...
        }).ContinueWith(async (a) =>
        {
            if (a.IsFaulted)
            {
                var dialog = new MessageDialog("Something went wrong!\nError: "
                           + a.Exception.Message);
                await dialog.ShowAsync();
            }
            else
            {
                var dialog2 = new MessageDialog("Everything is OK: " + a.Result);
                await dialog2.ShowAsync();
            }
        }).Unwrap();

In this machine I don't have Windows 8 so I tested in Windows 7 but I think is the same. *Edit as stated in the comments its needed .Unwrap(); in the end for the await to work
