A low-level CLI tool in Python for inspecting .NET serialized objects as per MS-NBRF and dumping their contents as XML.

The implementation is robust, but it's not 100%-complete, as it covers only fields I've actually stumbled upon - if the code doesn't work for you, please report an issue with a test sample so that I can add support for it.

Example usage:

python3 -m net_deserializer ./test.dat

Example output:

<Root>
    <SerializedStreamHeader>
        <RootId>1</RootId>
        <HeaderId>-1</HeaderId>
        <MajorVersion>1</MajorVersion>
        <MinorVersion>0</MinorVersion>
    </SerializedStreamHeader>
