Since MT 4 version still has some bugs for WCF services, I would downgrade it to 3.2.6.
I've recovered this old version but now it doesn't work because I have a more recent mono-framework version. What steps do I have to follow for disinstalling mono-framework 2.10.1_3 and recovering the old one?
Thank you. Regards.
Update: For those interested in, rembember to uninstall previous mono version. See this link: Uninstall Mono
