[Mono-devel-list] Can mono have methods(etc) not present MS implementation?

[Alexandre Gomes]

Hi,

My question is simple, can we do something on a MS controlled namespace
that is not part of the default implementation? Of course raising a mcs
warning telling something like "This method will make your app not to
run on MS.NET".

This comes from a desire to introduce something in CodeDom, for instance
for a Method I wish it to be able to contain more info than the default
like SourceCodeLocation (line/column).

What do you advice, to create a fork and keep patching it to stay sync
with mono tree or use what I proposed?
