The documentation for upgrading output redirection from Python2 suggests using a class which is internal.

The documentation (https://github.com/IronLanguages/ironpython3/wiki/Upgrading-from-IronPython2#redirecting-output) suggests when writing output to a TextWriter it is wrapped in a Microsoft.Scripting.Utils.TextStream. Although that class is implemented in Microsoft.DynamicLanguageRuntime, it is internal and so not available to use in my project. Is there an alternative (other than copying the code for Microsoft.Scripting.Utils.TextStream into my project)?
