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

When it comes to .NET, if you're releasing a Windows Forms application (or any application where the client has the Portable Executable file), it's able to be cracked.

If you want to stick with .NET and want to minimize the chance of having your source code taken, then you may want to consider deploying it as an ASP.NET application across a webserver, instead of making it a Windows Forms application.
