[Mono-dev] Controls in HTML comment block behave different in .Net and Mono

Fri Feb 3 10:00:16 EST 2006

MS.Net is always the right behaviour, even if unlogic or buggy. I guess
thats the mono ASP.Net parser ignoring everything placed between comments...
seems like the behaviour should be process it but don't show it.
