Licensing / Code protection

[2Wires]

Hi together,
I want to release my application but not without having it secured.
Since .NET is really easy to decompile and read, I want to secure the code by an obfuscator or other solution.
Please post some experiences you have with products.

And second I want to introduce a licensing method but I have no real clue how to do that secure. If I just check a key and return true or false, it is so easy to hack.
Perhaps you have some experience with it.

Tanks in advance

I haven't personally used it, but I've heard good things about Xheo|Licensing (http://www.xheo.com/products/enterprise/licensing/).
