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.

Hi, I’ve worked deeply with .NET internals, IL rewriting, and decompiler behavior, and I can design a custom obfuscation pipeline that goes well beyond DNGuard’s default profiles. The focus would be on source-level protection only—aggressive symbol obfuscation, control-flow transformation, string/metadata encryption, and targeted anti-decompilation techniques combined in a way that meaningfully degrades tools like dnSpy and ILSpy without destabilizing runtime behavior. I can deliver this as a repeatable build step (MSBuild task or CLI) that slots into your existing Windows CI pipeline, along with clear documentation and configuration options. As requested, I’ll include a proof-of-concept obfuscation of one assembly plus a concise comparison showing how the output resists decompilation relative to DNGuard. This is the kind of low-level, defensive engineering I’m comfortable with, and I’m happy to discuss tradeoffs between protection strength, runtime overhead, and maintainability before implementation.

Hi there, I understand the importance of keeping your C#/.NET application source code confidential and the limitations of existing obfuscation tools like DNGuard. My experience in developing advanced obfuscation strategies aligns perfectly with your requirements. I propose a tailor-made obfuscation system utilizing robust techniques such as symbol renaming, control-flow mutation, string and metadata encryption, anti-decompilation stubs, and tamper detection. This approach will clearly outperform DNGuard's default profile, ensuring maximum protection for your source code. I will create a repeatable build process, whether through an MSBuild task, CLI, or Visual Studio plug-in, to seamlessly apply the obfuscation to future releases without manual intervention. Clear documentation on configuration options and runtime components will accompany the deliverables. Having worked on custom obfuscators and reverse-engineering .NET internals, I am well-equipped to handle this project. I will provide a small proof-of-concept showcasing the enhanced decompilation resistance compared to DNGuard output. Let's discuss how I can tailor a solution specifically for your needs. Looking forward to the opportunity to work together. Zlatko

Hi, You’re right—most commercial .NET obfuscators (including DNGuard defaults) rely on predictable transforms that seasoned reversers can still read through. If the goal is actual resistance, not checkbox protection, a tailored pipeline is the only way forward. I’ve worked deep in .NET IL, metadata, and JIT behavior, including custom obfuscation layers and reverse-engineering of popular tools to understand where they fail. What I’d deliver: A custom obfuscation strategy focused strictly on code protection (no licensing/resources touched) Combined techniques that outperform DNGuard defaults: Aggressive symbol & metadata rewriting Control-flow mutation at IL level (opaque predicates, dispatcher flattening) String & metadata encryption with runtime decoding Anti-decompilation stubs (invalid IL patterns tolerated by CLR, hostile to dnSpy/ILSpy) Tamper detection tied to method bodies / metadata tables A repeatable build workflow (MSBuild task or CLI) compatible with your existing Windows CI Clean, explicit documentation of configuration knobs and runtime dependencies Proof-of-concept: One of your assemblies obfuscated using the custom pipeline A short comparative report showing decompilation results vs DNGuard (readability, CFG recovery, symbol leakage) I’m comfortable mixing custom IL rewriting, vetted open-source components, and (if approved) commercial SDKs—always license-clean and auditable.

Hello There, I’ve built custom .NET obfuscation pipelines for proprietary C# apps where off-the-shelf tools like DNGuard weren’t strong enough. I’ve worked directly with IL rewriting, metadata manipulation, control-flow mutation, string encryption, and anti-decompilation tricks that significantly raise the bar for tools like dnSpy and ILSpy. I can deliver a repeatable MSBuild/CLI workflow, clear docs, and a real before/after comparison showing stronger resistance than DNGuard. Let's get in touch Thanks

Hello, I can deliver a custom, source-code–focused obfuscation solution that goes well beyond DNGuard’s default profile. My approach combines multiple complementary techniques—aggressive symbol renaming, control-flow mutation, string and metadata encryption, anti-decompilation stubs, and tamper-detection logic—to significantly raise the cost of reverse engineering while keeping runtime impact minimal. The obfuscation pipeline will be designed as a repeatable build process, available as an MSBuild task or CLI (with optional Visual Studio integration), so protection can be applied consistently to all future releases without manual intervention. Configuration will be flexible and well-documented, allowing you to tune protection strength per assembly or build type. I will provide clear documentation covering configuration options, build integration, and any required runtime components. As a proof of concept, I’ll obfuscate one of your assemblies and include a short technical report comparing its decompilation resistance against DNGuard output, highlighting concrete improvements and trade-offs. I focus on practical, production-ready protection—not black-box tools—so you retain full control over your build and release process. Looking forward to discussing details. Best regards, Jitender K
