1) Make sure you are using the Unity3d "tuned" version of JSON.Net. You can find the latest version here: Json.Net.Unity3D. This version does not make use of dynamic code - thus is "safe" for Ahead-of-time compilers.

2) Make sure you add the correct preservation lines into your Unity3D "link.xml" file:

<linker>
  <assembly fullname="AssemblyName.Common">
     <type fullname="AssemblyName.Common.*" preserve="all" />
   </assembly>
</linker>

The * will ensure that all namespaces as well as all classes are preserved - and will not be stripped.

That should do it.
