This Python 3 library parses .NET Remoting Binary Format (NRBF) contents and converts them to Python data structures. Not all data types are supported. NRBF is what the BinaryFormatter class produces.

A typical example to use it is:

from net_nrbf import File as NrfbFile

with NrfbFile(file_path) as nrfb:
    data = nrfb.convert()

The first argument to File can be a file path or a file-like object. Use File.from_bytes() to convert from bytes objects.
