The above line is line 10, or the following line?

Regardless, since LANReveal is a namespace, LANReveal.WorkCompleted must
be a type, probably a delegate (based on how you're using it). If this
is the case, you're missing a "new" keyword:
w.completed += new LANReveal.WorkCompleted (m.writeToCMDLine);
The only way to avoid the "new" keyword would be to use C# 2.0 features,
such as implicit method -> delegate conversions, in which case you could
w.completed += m.writeToCMDLine;
I'm not sure why your code compiles on .NET. Maybe it's a CSC bug? Or
(more likely) my assumptions are wrong, and something else is to blame.
(The primary assumption I made is that LANReveal is a namespace, but it
could also be a nested type within a namespace --
LANReval.LANReveal.WorkCompleted could then be a method. But nesting a
type within an identically named namespace is just...weird.)
