On earth of software program progress, shielding your mental assets is essential. When establishing .Internet apps in C#, one particular common threat is code reverse engineering. Instruments like ILSpy or JetBrains dotPeek allow for any one to decompile your compiled .Internet assemblies back again into human-readable code. This tends to expose your business logic, algorithms, and sensitive details. To avoid this, builders typically use obfuscators—instruments which make the decompiled code obscure and reverse-engineer.

Luckily, you don’t have to have to interrupt the bank to protected your C# code. Several absolutely free obfuscators can assist safeguard your .NET programs. On this guide, we’ll take a look at a few of the best free of charge obfuscators accessible and provide tips on deciding on the proper one particular for your job.
