Thanks that was exactly the nudge I needed. Removing the callback and userstate did the trick.

There is a way to add known types, but since this was working in DF2010 it's much more likely that the method call isn't quite right.
 
This signature has always been a bit ugly.  Before, you needed to supply a callback and user state, even if null, and then your RPC method arguments.  So something like this:
  manager.InvokeServerMethodAsync("SomeServerType", "SomeMethod", callback, userState, arg1, arg2, ... argN)
 
Now you can instead do:
  await manager.InvokeServerMethodAsync("SomeServerType", "SomeMethod", arg1, arg2, ... argN);
 
If you're supplying a CancellationToken if would come before your arguments.  If you're also referencing the DevForce 2012 Compatibility pack that might confuse things further.

We are getting an error when we call InvokeServerMethodAsync:

Type 'System.Object[]' is not known to the serializer.

This happens when we pass in parameters to the object[]. If we pass in null then the invoke call will go through. 

Is there a way to add System.Object[] to the serializer?
