With other words: regressions on +all profiles. + +I'd rather fix bug #78593 and its sibling #81465 for +Mono 1.2.6 and introduce DateTime.ISerializable with +Mono 1.2.7. + +--- +A few words about DateTime.ISerializable (executive summary :-): + +This is only used when a DateTime is directly serialized. +i.e. it's not part of another class: + +new BinaryFormatter().Serialize (stream, DateTime.Now); + +In this case, DateTime is not treated as a primitive type, +maybe because it's the root of the serialization graph. + +I've tested this exceptional case on MS.NET and it seems that +their implementation is struggling as well (the MS.NET 1.1 SOAP +formatter cannot handle 2.0 DateTimes). + +IMHO, it's not worth the trouble. +--- + _______________________________________________ mono-bugs maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-bugs
