Advanced .NET Obfuscation Solution

I have a C# / .NET application whose source code must stay confidential. Commercial tools like DNGuard still leave traces I consider readable, so I’m looking for a stronger, tailor-made obfuscation system.

Here’s what I need you to deliver:
• An advanced obfuscation strategy focused on protecting source code only—data, resources, licensing, and activation aren’t in scope.
• Robust techniques such as symbol renaming, control-flow mutation, string and metadata encryption, anti-decompilation stubs, and tamper detection, combined in a way that clearly outperforms DNGuard’s default profile.
• A repeatable build process (MSBuild task, CLI, or Visual Studio plug-in) so I can apply the protection to future releases without manual steps.
• Clear documentation explaining configuration options and any runtime components the app will rely on.
• A small proof-of-concept: one of my assemblies obfuscated with your method, accompanied by a short report comparing its decompilation resistance to DNGuard output.

I already have automated builds on Windows; feel free to recommend open-source libraries, commercial SDKs, or your own code, as long as the final workflow is smooth and license-compliant.

If you’ve built custom obfuscators, reverse-engineered .NET internals, or cracked open popular tools, that’s perfect context to mention in your bid.
