Remove List<int> from the list of supported SerializationInfo types in the CSLA 9 upgrade guide, and correct the serialization.md claim that List<T> and Dictionary<K,V> are supported. These standard .NET collection types are not directly serializable - users should use MobileList<T> or MobileDictionary<K,V> from Csla.Core instead. Fixes #4680 https://claude.ai/code/session_011R3Y2CSgCZrDwdVacjARaW
CslaBinaryWriter/Reader explicitly handle List<int> (CslaKnownTypes.ListOfInt), so it IS a valid type for use in custom serializers via SerializationInfo.AddValue. Updated the warning to clarify that other generic collection types (List<string>, Dictionary<K,V>, etc.) are not supported. https://claude.ai/code/session_011R3Y2CSgCZrDwdVacjARaW

Summary
Updated documentation to clarify that standard .NET collection types (
List<T>,Dictionary<K,V>, etc.) are not directly serializable byMobileFormatterandSerializationInfo, and to guide users toward appropriate alternatives.Key Changes
serialization.md: Removed misleading statement that
MobileFormattersupportsList<T>andDictionary<K,V>. Added warning box clarifying that standard collection types are not directly serializable and recommendingMobileList<T>,MobileDictionary<K,V>, or custom serializers as alternatives.Upgrading to CSLA 9.md: Added warning box documenting that generic collection types beyond the explicitly supported list (such as
List<string>,Dictionary<K,V>) are not directly serializable bySerializationInfo, with guidance on using CSLA collection types or custom serializers.Details
These documentation updates correct a gap in guidance that could lead developers to attempt using unsupported collection types in serializable business objects. The changes direct users to the proper solutions: CSLA's built-in mobile collection types or custom serializer registration.
