“Link Assemblies” task failed unexpectedly issue while building release version of app in Xamarin

I want to release my android app. When I try to build it, it gives me the following error:

Severity    Code    Description Project File    Line    Suppression State
Error       The "LinkAssemblies" task failed unexpectedly.

I have deleted the xamarin.ios reference in the app.droid but that didn't work. Any suggestions? I also tried setting the android versions to what ever I found on the internet. I also tried updating PCL version but still nothing. Am I missing something?

EDIT: In my project I also have a portable library linked to the android project with ios code in it.

I'm not sure why you might have Xamarin.iOS referenced in your Xamarin.Android project. But the issue is that you have some type of reference there when it shouldn't be. Your PCL should not have any Native code inside it.

The Linker does not do any work when it's a Debug configuration. When you change to Release it will try to find assemblies that you do not use and strip them out. For some reason you have an iOS assembly in your Android project.

Check that your Xamarin.Android and PCL project do not reference Xamarin.iOS in anyway. The native projects should only be referencing the PCL(Which contains no Native Code inside)
