Generating C# bindings for native Windows libraries

When writing system applications in C# we often need to interact with the system APIs directly. And it has always been a challenge to write proper PInvoke signatures. However, with the introduction of the Windows metadata project and later, cswin32, things changed significantly. In this post, I will walk you through the steps required to generate C# bindings for a sample native library. I picked Detours, because I needed it for withdll, my new tool inspired by the withdll example from the Detours repository. The post by Rafael Rivera describing how to create bindings for Rust language helped me tremendously in writing this post (and bindings 😊).
