Description Laza 2017-09-20 23:35:38 UTC
I have just inherited a project that I need to compile on my Mac, Installed the latest Mono, just getting one error.

'Message' does not contain a definition for 'LookupId' and no extension method 'LookupId' accepting a first argument of type 'Message' could be found (are you missing a using directive or an assembly reference?)

The code in question is simply referencing: message.LookupId where message is an instance of "System.Messaging.Message"passed in as a parameter.

Is this supported in Mono
