[Mono-list] webHttpBinding WebInvoke POST issue

[Atsushi Eno]

Hello,

NotSupportedException is not NotImplementedException, so it is likely 
intended to actually throw that error. It is still possible that the WCF 
internal goes wrong path and reaches that WriteMessage() part, but 
without actual code to examine I cannot guess for sure.
