My next observation is using the PhotoChooserTask.
The associated graph is as follows :-
As you can see, we have Storyboard start when the button is tapped to launch the task.
We then have a period of inactivity before the Image is loaded.
The Image loads has a flag dictating the Image is loaded into the Image control.
If you have any experiences to share with using the Performance Analysis Tool, I would be very interested to hear them.
More to follow...
