The XmlSerializerVersionAttribute type exposes the following members.

Constructors
  NameDescription
Public method XmlSerializerVersionAttributeInitializes a new instance of the XmlSerializerVersionAttribute class.
Public method XmlSerializerVersionAttribute(Type)Initializes a new instance of the XmlSerializerVersionAttribute class for the specified type.

Properties
  NameDescription
Public property NamespaceGets or sets the common language runtime (CLR) namespace of the assembly.
Public property ParentAssemblyIdGets or sets the identity of the parent assembly.
Public property TypeGets or sets the type that the serializer operates on.
Public property TypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

Remarks

The .NET Framework XML serialization infrastructure dynamically generates derivations of XmlSerializer that are optimized to serialize user-defined types. The serializers are stored in assemblies that can be reused for efficient serialization.

The XmlSerializerVersionAttribute attribute stores version information about the parent assembly for which a set of serializers is generated. Later, when the XmlSerializer constructor is called, the infrastructure attempts to locate the pre-generated assembly. If the infrastructure finds an assembly with a matching name, the assembly is loaded and the infrastructure checks XmlSerializerVersionAttribute for a match between the found assembly's version and the current version of the parent assembly. If the version does not match, the found assembly is not used. Instead, a temporary assembly is generated for the serialization.
