Difference between DataContractSerializer vs XmlSerializer

Question

I was going through WCF Fundamentals, Can anybody tells that under which scenarios should we use DataContractSerializer and XmlSerializer?

Answer 1

DataContractSerializer

• Is meant to be used for serialization/deserialization of class in WCF service to and from either JSON or XML.
• serializes properties and fields.
• Is faster than XmlSerializer
• Doesn't control how xml is generated. Should not be used when full control on generated XML structure is required

XMLSerializer

• XmlSerializer is only for XML serialization
• Supports full control over the XML structure
• Serializes only public properties
