XmlSerializer fails while serializing a type that hides an accessible member with an inaccessible one

Scope

Minor

Version Introduced

4.5

Source Analyzer Status

Planned

Change Description

When serializing a derived type, the xref:System.Xml.Serialization.XmlSerializer?displayProperty=name can fail if the type contains an inaccessible field or property that hides (via the 'new' keyword) a field or property of the same name that was previously accessible (public, for example) on the base type.

  • Quirked
  • Build-time break

Recommended Action

This problem can be solved by making the new, hiding member accessible to the xref:System.Xml.Serialization.XmlSerializer?displayProperty=name (by marking it public, for example).

Alternatively, the following config setting will revert to 4.0 xref:System.Xml.Serialization.XmlSerializer?displayProperty=name behavior, which will fix the problem:

<system.xml.serialization>
	<xmlSerializer useLegacySerializerGeneration="true" />
</system.xml.serialization>
