momo7807, if I understand obfuscation correctly, it just converts your program into a native equivalent. So there probably is a way to de-obfuscate your program. Nothing is, sadly, foolproof these days.
Visualstudio is right though. Sadly, if you build a windows forms application, it loads a hole lot of assemblies that are not needed for your program. Mscorlib contains hundreds of DLLs it loads by default, and I don't know how to change that.
"On two occasions I have been asked [by members of Parliament!]: 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out ?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question." — Charles Babbage.
