Use AI to serialize to JSON You can use AI tools, such as GitHub Copilot, to generate code that uses System.Text.Json to serialize to JSON. You can customize the prompt to fit your object fields and serialization needs. Here's an example prompt you can use to generate serialization code:
This article provides information about .NET serialization technologies, including binary serialization, XML and SOAP serialization, and JSON serialization.
By default, both source generation modes (metadata-based and serialization optimization) are used if you don't specify one. For information about how to specify the mode to use, see Specify source generation mode later in this article.
Serialize and Deserialize methods on BinaryFormatter, Formatter, and IFormatter are now obsolete as warning. Additionally, BinaryFormatter serialization is prohibited by default for ASP.NET apps.
Serialize properties of derived classes Beginning with .NET 7, System.Text.Json supports polymorphic type hierarchy serialization and deserialization with attribute annotations.
Source generation can be used in two modes: metadata-based and serialization optimization. This article describes the different modes. For information about how to use source generation modes, see How to use source generation in System.Text.Json.
Serialization is the process of converting an object into a stream of bytes in order to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization.
The following list shows just some examples of the types of customizations you can make to serialization and deserialization: Serialize private fields and properties.
Changes to support source generation The following example shows the code added to the Program.cs file to support JSON serialization source generation:
