Protect .NET code from reverse engineering?

Question

Obfuscation is one way, but it can\'t protect from breaking the piracy protection security of the application. How do I make sure that the application is not tampered with,

Answer 1

You can..

Microsoft SLP ServicesInishTech's Software Potential offers the ability to help protect code without affecting the functionality of your applications.

UPDATE: (Disclosure: I work on Eazfuscator.NET) What makes Microsoft SLP ServicesSoftware Potential different is the ability to virtualize the code, so you definitely can. Several years passed since the question was originally asked; today there are more products available that also work on a similar basis such as:

• Agile.NET
• Eazfuscator.NET
