Problem with "Link SDKs only" and iOS

DirkWilhelmDirkWilhelm USMember ✭✭✭

Hello,

i'm developing an forms app that uses AutoMapper. In debug mode using then "none" linker behavior, the app starts fine on an iOS device.

But when i set the linker behavior to "Link Framework SDKs only" to reduce the ipa file size, my app crashes on startup on an ios device.

In the XCode device console i get this error message:

MessageSystem.ArgumentNullException: Value cannot be null.Xamarin Exception Stack:

I tried to exclude automapper and system.core from the linker as described in the xamarin documentation, but that doesn't seem to work, i still get that error message.

I'm using the latest stable xamarin release.

Besides from not using the linker, what can i do to resolve my problem?
