[Mono-dev] serialization "not implemented"

[Andreas Nahr]

No, it's not specific problem with your usage. It's just not implemented in
Mono.
http://github.com/mono/mono/blob/master/mcs/class/System.Core/System.Collect
ions.Generic/HashSet.cs#L545

BTW: I don't know if the Mono Migration Analyzer is able to detect
Serialization problems, but it seems it doesn't.
