Protecting IP is good thing when doing this doesn't use police methods. What do you think about Reflector? Very useful tool, huh? But it is like spy looking at which methods you are investigating. Each link in the decompiler method that links to class name looks like this :
http://www.aisto.com/roeder/dotnet/Default.aspx?Target=code://mscorlib:2.0.0.0:b77a5c561934e089/System.Void It's like when you are using microscope somebody else looking at the same things that you are looking. Not friendly.
To check this you can go to Reflector, select class, or method code and copy it. After that go to VS to HTML designer and use command Paste Alternate from Edit menu. Have a nice digging with Reflector :))
