Tamper Protection on .NET Assemblies

Question

Many obfuscation tools today offer tamper protection. We gave it a try but it was not applicable in most of our real-world cases.

Does it worth to invest time in this technologies or the added protection level is something that hackers can break in minutes as all the rest?

Answer 1

All code that runs on the client can be changed and tampered with, the tools will only make it a little harder to do. First of all find out if there is a business case in tampering your code anyway. If so, then decide if you should ship it at all or provide the critical code as a service.
