IronPython under Linux problem with standard JSON serialize and de-serialize

Problem:
When needing to have JSON tools in IronPython, you are normally guided to use the System Web Extensions:-

clr.AddReference('System.Web.Extensions')

This will not work under Linux, because this is a Microsoft library.

Under linux you get the error:-

Could not execute script 'Copy to Clipboard': Could not add reference to assembly System.Web.Extensions

Solution:
Use the inbuilt IronPython json tools:-

import json
Document.Properties["output1"] = json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
Document.Properties["output2"] = json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True)

In fact this should be the default solution, as it will work for both Windows and Linux.
