[Mono-dev] Very simple typed dataset serialization fails

[marcos b]

Hi Rafael. I know typed datasets and datasets have some issues, but prior to
the advent of Linq it had many benefits in respect to sorting, filtering and
querying in general (and it still has some benefits when you want versioning
and batch update).

The problem is that I'm trying to migrate a 1 millon LOC program. So it's
very difficult to replace typed datasets with plain objects in a timely
manner (I'm just evaluating how hard would be to migrate our solution to
Mono)

I will post the bug hoping someone find a solution while I continue testing
my application for other issues.

Thank you
