Hi Nadeem, Nice, thanks. Now I can see the problem. So far I have "implemented" OnWriteBodyContents() as to write dummy output, and the exact problem is gone (done in git master/mono-2-10 branches). There is another issue, looks like .NET WCF treats Stream parameter in special manner that we didn't have done yet. I'll investigate that issue too.
