How can I get Linkskip to work for the below error when Linker behavior is set to "Link Framework SDKs Only"

I'm getting the following error when the Linker Behavior is set to "Link Framework SDKs Only".

Can't resolve the reference 'System.Void Newtonsoft.Json.Serialization.DefaultContractResolver::set_IgnoreSerializableAttribute(System.Boolean)', referenced from the method 'System.Void System.Net.Http.Formatting.JsonContractResolver::.ctor(System.Net.Http.Formatting.MediaTypeFormatter)' in 'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'.

My build compiles when the linker Behavior is set to "Don't Link".

I've tried:

--linkskip=System.Void Newtonsoft.Json.Serialization.DefaultContractResolver

--linkskip=System.Void Newtonsoft.Json

--linkskip=System.Void

--linkskip=Newtonsoft.Json

--linkskip=System.Void System.Net.Http.Formatting.JsonContractResolver

--linkskip=System.Net.Http.Formatting.MediaTypeFormatter

Any suggestions?

Thanks
