Serialization Programming Model for WCF Similar to ISerializable (also supported by WCF) Can generate from/to WSDL/XSD using

svctool Example:

[DataContract]public class ComplexDataContract{ [DataMember] string name; [DataMember] System.Version version; [DataMember] System.IO.FileInfo fileInfo; [DataMember] System.Collections.Generic.List<System.Uri> uriList; [DataMember] System.Data.SqlTypes.SqlInt32 sqlInt; [DataMember] System.Drawing.KnownColor knownColor;}

xs:import references a namespace, but also a physical document

Namespaces in .NET assembly are not bound to the physical document or XML namespace.

Import parent XSD then import chiid XSD. Duplicate types created.

SvcTool parameter /references: Allows parent assemblies to be

referenced Searches for duplicate types

“Custom Tool” for Visual Studio Generates code when XSD is edited Integrates with project system

SvcTool is limited: Only supports basic types in parent

element/type▪ boolean, byte, dateTime, decimal, double,

float, int, long, short, unsignedByte, unsignedInt, unsignedLong, unsignedShort▪ Critical: Fails if xs:string is included

Option B: Use XsdDataContractImporter Would have better performance too
