Best .NET obfuscation tools/strategy

Hi there,

I'm ending my development of a small business application, using NET 4.0.

I would like to know which tool are you using to prevent your code to be decompiled/stolen.

I know that exists a few tools in the market, but I would like to know the best ones, keeping in mind that I'm using reflection to access properties and some methods

Thanks

here is no such possibility. Dotfuscated and packed application can be unpacked and undotfuscated by professional, and it can be reversed. Any program can be hacked, any .net program can be opened, because for that normal work needed il code, which can be easily opened.

You can use Visual Studio's Dotfuscator.
