C# Desktop App Security Hardening - Obfuscation & License Protection

We have a fully completed C# (.NET/WPF) desktop application called Tweaks Lab Client — a PC optimization tool with a HWID-based license key system. The application is finished and functional, but security was not a priority during development, and we now need to fix all the vulnerabilities before wider distribution. We're looking for a developer/security specialist to: Obfuscate the compiled application (ConfuserEx2 or equivalent) — rename symbols, encrypt strings, add control-flow obfuscation Review and harden our license validation system (HWID-based) — currently the check may be too easily bypassed or patched, we want a more robust client-server validation flow Add anti-tampering protection to detect if the binary has been modified/patched Identify and fix any hardcoded secrets, API keys, or sensitive strings currently exposed in the compiled code General security audit of the application — flag anything else that could be exploited (reverse engineering, memory dumping, debugger attachment, etc.)
