C# DLL Decompilation Insight

I have a single C#-based .dll that I need to reverse-engineer so I can study its inner workings and document how the classes, methods, and data structures fit together. This task is strictly about understanding the code—no modifications or redistribution are planned.

Here’s what I’d like back from you:
• Human-readable C# source that opens cleanly in Visual Studio (or a comparable IDE)
• Any accompanying project/solution files you generate while decompiling
• A concise technical note that walks me through the main namespaces, entry points, and any non-obvious logic you notice

Use whatever tooling you trust—dnSpy, ILSpy, dotPeek, or your own scripts—as long as the output is accurate and builds without errors. If the library is obfuscated, please outline the steps you take to de-obfuscate it so I can replicate the process later.

I’ll provide the .dll immediately upon kickoff and will be responsive for quick clarifications or testing. Let me know your estimated turnaround time and any prerequisites you’ll need.
