C# (Classic .exe, Windows 10, Windows Phone etc.) Protection

[delidolunet]

Actually I wanted to discuss this not for a paid product, for example for Windows Phone platform there is an instagram client which is better than official instagram application, after that in a few weeks people got it's source code, and publish it with an another name. This was what I don't want to experience.

After Microsoft released .net native, I think decompiling apps will not be this much easy anymore.

Also if you use Eziriz and Smart Assembly kind of softwares to protect your .net apps, they're getting more slower than ever. While .net is not a super-speed platform, putting some extra slowing down factors looks like a bad idea.

Thanks for your thoughts.
