title: OnNavigatedTo and async/await in Windows Phone
body: <p>The question is rather about best practices. I have a PhoneApplicationPage with OnNavigatedTo overriden, and I want to await some async call there. What will happen to navigation when some call is awaited? My assumption is that navigation will not complete until the awaited call returns. By extension, it will render the async nature of the call useless. Is it true?</p>
  
  <p>Another thing is that OnNavigatedTo returns void, and I cannot change this to the Task. This, in turn, means that any exception inside my async method will crash the app completely. Of course it's possible to catch exceptions, but again I'm concerned about if it's a good approach.</p>
  
  <p>To sum up: anyone uses async/await in OnNavigatedTo? What is your experience? How likely is that you'll recommend it you to your friend or colleague? :)</p>
