On the earth of software program growth, guarding your mental house is very important. When producing .Internet programs in C#, just one typical menace is code reverse engineering. Resources like ILSpy or JetBrains dotPeek permit anyone to decompile your compiled .Web assemblies back again into human-readable code. This may expose your enterprise logic, algorithms, and sensitive information and facts. To forestall this, developers usually use obfuscators—resources which make the decompiled code difficult to understand and reverse-engineer.

Thankfully, you don’t require to break the financial institution to secure your C# code. Quite a few free obfuscators can assist safeguard your .NET purposes.
