It's far easier. The thing is: most people don't program for
obfuscation, so their .exe doesn't have solely internal classes
and methods. This means that a lot of code is not really obfuscated. Even when
it is, it's easy: when you use a 3rd party assembly,
for example Xheo, you have to call it at some point. Just hunt for the method
call, it's there, unobfuscated.
In a C++ dll this is harder because you just have offsets of in-memory
mapped libs, which requires sophisticated tools to
get a proper overview.

Have you looked at these libs? I looked into them to see if I should
roll my own protection code or buy a license from one
of these, though it was, sorry to say it, not very hard to track down where
they stored the trial info for example, one of the weak
spots in licensing. The other weak spot, which is out of their hands, is that
calls to their lib can't be obfuscated well enough.
