UWP BinaryFormatter alternatives?

Getting an error called : Assets\HoloToolkit-Preview\SpectatorView\UnityARKitPlugin\ARKitRemote\ObjectSerializationExtension.cs(3,47): error CS0234: The type or namespace name 'Binary' does not exist in the namespace 'System.Runtime.Serialization.Formatters' (are you missing an assembly reference?)

with the script from Mapbox

Code (CSharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4. using System.Runtime.Serialization.Formatters.Binary;
5. using System.IO;

7. namespace Utils

38.                 memStream.Write(byteArray, 0, byteArray.Length);
39.                 memStream.Seek(0, SeekOrigin.Begin);
40.                 var obj = (T)binForm.Deserialize(memStream);

is there any way to rewrite this so it is not dependent on the System.Runtime.Serialization.Formatters.Binary? sorry i'm not that great with creating scripting in general, was just hoping there was something we could use besides BinaryFormatter, already looked at trying to incorporate JSON or XML instead, just could not understand it tbh

The scripting also requires us to use the .Net instead of the IL2CPP.

 

We found a workaround to this error, we made a new unity project and just transferred the map from another project since we made the map [executeineditmode] we could transfer it without having to incorporate the map box package to the new unity project and avoid all the scripting that caused these errors.
