Re: How to Prevent reverse engineering .NET

Adding to Jon's comments:

'Prevention' is a subjection term.

Putting special locks on the doors and windows of your house will discourage
a reasonably large percentage of burglars, but a determined burglar will get
in if he really wants to.

Its' a matter of the 80/20 rule however I feel that with obfuscated code it
would be more like 99/1.

While security is important, overdoing it can easily lead to rendering the
whole thing unusable.
