[Mono-list] WCF Hosting Problem

Thu Jul 21 12:53:01 EDT 2011

Here's how I fixed my WCF woes: I scrapped everything WCF I had done
and went with ASMX.  I struggled with configuration for quite some
time myself.  And then, even when I found the magic combination of
configuration such that initialization succeeded, I was getting
run-time WCF issues.  I spent nearly a month on it before giving up.
Note that I am running the latest, stable Mono source release.  ASMX
is totally solid (and even includes a nice web interface to manually
test your services).

Atsushi, I'm usually very good with filing bugs but in this case there
were so many variables that I really couldn't write a better bug than
"this is totally broken".  If I had a small, reproable test case then
I would've been happy to.
