Searching for a maintained binary diff/patch tool or library

Question

I am looking for an executable (or a library that I might embed in C# or via Managed C++ into the C# project) to create binary diff files for two folders and their contents and a patch tool to apply those patch files as well targeting Windows.

This SO post refers to various tools such as bsdiff/bspatch which is highly dated. The 3rd party executable that is available here does not work when trying it out though. Another variant that is not compatible with the original is the following. Unfortunately it relies on bzlib and certain Linux headers and I wasn't really able to set it up accordingly under Visual Studio.

Anyways, all tools and posts are about 8-10 years old and I'd like to know which tools and libraries are currently maintained that I might take a look at.

Answer 1

I have been experimenting with Octodiff and I am impressed and will most likely be using it in production.
