Yeah, I'm noticing that, too. But, at least in my case, it has to be fixed. :P
Although, I can't really think of anything outside of this particular case that
might also need to be fixed. Only in-process cross-domain calls would try to
take advantage of having the same assembly in both AppDomains. If it's in the
same domain, it *is* the same assembly, and if it's not in the same process,
then you can't take the shortcut anyways. What other areas can you think of that
might also need to be fixed?
I find it odd that the author took pains to call the correct method, but failed
to see that late-loading the method's pointer (the apparent function of
CEE_MONO_LDPTR) does no good if you assume you're working with the same
assembly-- you'll just get the same pointer again.
In fact, it may be as simple as introducing a late-binding mechanism into the
