Detect when user returns from using EmailComposeTask?

I noticed the user is redirected back to our app after sending an email using the EmailComposeTask. Is there maybe a Completed event handler for this or someway to determine when the user returns 开发者_C百科back to our app?

The NavigatedTo event will be raised when the control comes back to your page.

Yes there is a completed event handler.

Here is how to do it for CameraCaptureTask. EmailComposeTask should be the same.
