Best Protection for .net Exe

[Rosan]

Can some one guide me or provide me high secure protector or packer for my .net application.

The best protection is not a packer nor a protector, it's a new project design that would allow a black-box on sensitive data

That is to say : put sensitive code on a remote server

So basically an application that needs internet connection for it to be able to access some resources.

Make server-side logic or learn c/c++

In the best case, you can pack your code natively with special packers
