The "LinkAssemblies" task failed unexpectedly after Xamarin Forms update to 3.1

I have recently updated my solution from Xamarin Forms 2.5 to 3.1. I have installed the package Prism.DryIoc.Forms 7.0.0.396 on the different applications (UWP, IOS, Android). Everything works as expected since the update with UWP but when I try to launch my Android project, it get this error :

I have never had to deal with LinkAssemblies before. The linking in my Android options is set to none. The code in my MainActivity.cs (Android) and App.xaml.cs has not been changed and is correct.

    This issue is caused by your changing major versions. For now you'll need to roll back to 2.X, we'll be updating to DryIoc 3 soon
