- Serializing and deserializing data in C#.
System.Xml.Serialization.XmlSerializer: Enables object serialization into XML documents and vice versa. It's straightforward to use but works only with public properties and fields and requires objects to have a parameterless constructor.
System.Text.Json.JsonSerializer: Introduced in .NET Core 3.0, provides high-performance, low-allocating, and standards-compliant capabilities to serialize and deserialize objects to and from JSON. It's part of theSystem.Text.Jsonnamespace.
System.Runtime.Serialization.DataContractSerializer: Part of the Windows Communication Foundation (WCF) and designed for serializing and deserializing objects as XML or JSON. It uses opt-in model throughDataContractandDataMemberattributes to specify what parts of an object should be serialized.
