Astsushi,
I promise I file bug reports when I find something and am able to
provide a decent test case:
http://bit.ly/nZp81a (granted a few of these "gillespie"s aren't me
but most are ... I ef'g hate bugzilla, btw ... but that's for another
time ;) It just so happens I haven't come across anything useful to
file about WCF.
I'm pretty sure I couldn't even get your most basic of basic examples
working for me:
http://veritas-vos-liberabit.com/monogatari/2009/12/mono-wcf-advent-day-6-aspnet-hosting.html
That's from 2009. Have you tried revisiting this example with the latest?
I wish I had the time to further investigate where exactly WCF was
breaking down for me but I just don't have that luxury right now. The
switch to ASMX fulfilled all my needs so I'm blissfully going down
that path. I know this doesn't help the Mono community at large, my
apologies. Hopefully at some point in the near future I can revisit
it and contribute back something useful.
