First of all it is important to understand the Metro Windows Store app lifecycle and Jeremy Likeness has perfectly covered the topic, go and read it.

As you can see there are a lot of details that should be taken into account:

  • is it a resume or a cold start?
  • the application state should be restored?
    • at which point?
  • is it a “charm” request?
  • is it a custom tile request?
  • is it a toast notification request?

So the question should be: is my role, as app developer, to handle all those possibilities? or my role should be to handle the application business logic?

Using Radical you can forget the most part of the question above and concentrate on the cool part of your application:

Any feedback is really appreciated.
