[Mono-list] my first c# program doesn't work :-(

[Candide Kemmler]

Hi,

To begin with, could somebody please tell me how to subscribe to this 
list ? I haven't found any hints about this on the go-mono website.

Have tried to make this incredibly simple program work, without success. 
No, sorry, this one works, but I had liked to have to threaded version 
run, which should if the commented part was enabled:

//        Connection con = new Connection ();
//        con.socket = s;
//        con.start ();

I keep having the following error:

Error..... #0: 0x0000b ldfld		in .Connection::handleConnection ()

Is it my fault or your fault, :-) ?

Apparently, everything collapses when trying to access the "socket" ivar 
in the Connection class...
Any help greatly appreciated.
