You can't. Ultimately, you can only make it harder, but you cannot stop it entirely.

As already shared you cannot stop entirely, but you can obfuscate and make it harder to reverse engineer.

Quote:
Dotfuscator can obfuscate your .NET assemblies to hinder reverse-engineering, while maintaining original application behavior.

Reference: Dotfuscator Community - Visual Studio | Microsoft Docs[^]

There are more such tools that provide different levels of security. You will have to find another if above does not suits you.
