We use Microsoft SLP Services Code Protector. Rather expensive but is included with some MSDN Subscriptions if you have one. It is way more advanced than Obfuscation. You get your own specific Permutation that is used to create intermediary code that only a specific virtual machine can interpret. This is all done automatically with a couple dlls you have to include in your project but for everything we have tried it can't be broken without having access to the original permutation. Something to look into.

I am working on a Home Improvements website and I want users to be able to submit articles to my site. Does CodeProject use their own custom code for article submission or do they use a third party? Can anyone recommend a good solution to use. Thanks in advance.
