.NET Compact Framework 2.0 SP2 Released
XmlSerializer serializes object members in order more closely resembling declaration order where no order is explicitly defined.
Previous Behavior: XmlSerializer would scramble the order of XmlElements in a serialized object unless the Order property was set on XmlElementAttribute and similar attributes.
New Behavior: XmlSerializer now takes care to preserve the order that members are reflected from serialized objects where no Order property is explicitly set. Note that where element ordering is important, explicitly setting the Order property is still recommended on both NetCF and .NET Framework to guarantee proper serialization order across platforms and versions.
