My Xamarin.iOS app was working fine until I deleted some packages that I didn't need anymore, and were preventing my app to build. Now my app builds, but it crashes on startup. In the application output:

Method not found: void Facebook.CoreKit.AppEvents.ActivateApp()

I have these packages still installed and up-to-date:

Xamarin.Facebook.CoreKit.iOS Xamarin.Facebook.CoreKit.CoreKit.iOS Xamarin.Facebook.GamingServiceKit.iOS Xamarin.Facebook.LoginKit.iOS Xamarin.Facebook.MarketingKit.iOS Xamarin.Facebook.PlaceKit.iOS Xamarin.Facebook.ShareKit.iOS

I am calling FacebookClientManager.Initialize(application, launchOptions) in my FinishedLaunching and FacebookClientManager.OnActivated() in my OnActivated

Try removing those nugets from solution. Then add them back in.
