OK, I found the solution.

-ext. However in case of WixDifxAppExtension.dll it isn't enough and difxapp_x64.wixlib needs to be passed as well. Wixlib is a collection of wixobjs. This is a bit unintuitive but it is what it is.You can adjust your code as below and it will compile:
project.LightOptions += "\"" + System.IO.Path.Combine(Compiler.WixLocation, "difxapp_x64.wixlib") + "\" "; project.BuildMsm();
project.LibFiles.Add(io.Path.Combine(Compiler.WixLocation, "difxapp_x64.wixlib"));
