Ummm - My startup is not being called until 17 seconds in. I can't speed up what isn't my code.
And my startup takes 0.4 of a second, so I don't need to speed that up. I just need it called sooner than 17 seconds in.

Say you have 17 things that have to run before the app "launches", each taking 1 second to complete. Maybe for 10 of those things, it doesn't matter when they run/finish. So, execute those 10 things in a new task and forget about them. Then your start up should only take 7 seconds. For example: var task = Task.Factory.StartNew(() => { //do your async work here }); On Wed, May 30, 2012 at 6:50 AM, Dean Cleaver <[email protected]<mailto:[email protected]>> wrote: Hi, My FinishedLaunching completes in about half a second. It's just taking 17 seconds before that gets called.

You should not be doing expensive initialisation synchronously for precisely this reason - iOS will kill your app if it takes too long. For example wrap code in a Task which will execute on the background thread. You need to ensure you only touch the UI from your main thread though, http://docs.xamarin.com/ios/advanced_topics/threading .
