To be a .Web developer, safeguarding your C# code is critical to preserving your intellectual property and protecting against reverse engineering. Though compiled .NET assemblies is often decompiled into readable source code, obfuscation features a method to increase a protective layer to your software package. Obfuscation tactics make your code tough for anybody to know and change, making sure your sensitive logic continues to be safe.
