I am very frustrated about the latest Xamarin upgrade (Jan 12) (and actually most previous upgrades).
The app I'm currently working on doesn't build anymore after the latest upgrade.
It did build and ran perfectly the day before.
Error MT2002: Failed to resolve "System.Void UIKit.UIPickerView::set_Delegate(UIKit.UIPickerViewDelegate)" reference from "Xamarin.iOS, Version=0.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065" (MT2002)
I don't use UIKit.UIPickerView in my code, I use UIImagePickerController directly, and again, it did work as expected before the upgrade.
Frankly, every time Xamarin announces an update, I'm scared to push the button.
I never know what to expect next. What will break now? What errors are introduced or reintroduced this time?
It comes to a point that, when I'm in a project with a deadline near, I NEVER push the update button.
I have missed deadlines (some with serious repercussions) by doing updates mid project and running into build issues, so I've learned my lesson.
IMHO, Xamarin should do way more quality-testing before releasing updates than they are doing now and don't rely on their -paying- customers to report / iron out bugs. I, as a freelancer -and probably many more clients with me-, have no time for that and simply refuse to be a guinea pig.
Working with Xamarin for several years now, with bussiness licenses for iOS / Android & MAC.
