[Mono-list] Deserialization issue when talking to webservice from mono

[Alan McGovern]

I really wouldn't be the one to ask about this, but the best bet is to:

1) Serialize the structure on .NET and save to a file
2) Serialize the structure on Mono and save to a file
3) Create a bug on http://bugzilla.novell.com and attach the two files and
the description of how they were created.

You should also reduce the structure to as small an item as possible to
reproduce the bug. For example if you have a List<ComplexObject> you should
try reproduce with just a List<int>, or just a ComplexObject. If the second
fails, then start removing properties from ComplexObject until you know the
one which is failing. If we know *exactly* what is triggering the issue,
it'll be easier/faster to fix.

Though if you want your application to work with any released versions of
mono, you need to investigate an alternative serializing form.

Alan.
