You may be able to fix this by adding this markup to the projects main link.xml file   <assembly fullname="Apple.Core" ignoreIfMissing="1" preserve="all"/>

i think this can be fixed by adding perserve markup to your project main link.xml   <assembly fullname="Apple.Core" ignoreIfMissing="1" preserve="all"/>

I had the same issue. It was fixed by adding perserve markup to our root link.xml   <assembly fullname="Apple.Core" ignoreIfMissing="1" preserve="all"/>
