System.Text.Json
System.Text.Json is a .NET library providing APIs for serializing, deserializing, reading, writing, and processing JSON data.
ASP.NET Core in Action, 3e
System.Text.Json is the .NET library for reading and writing JSON data.
- How it is used
- Handles JSON request binding and response serialization in ASP.NET Core minimal APIs.
- How deep it goes
- Explains automatic binding and selected serializer options, but defers broader model binding and advanced customization.
- Examples
- Uses Fruit and Product request models, Postman requests, serializer-option configuration, and an NSwag-generated client.
- What you can do after
- Apply it via ASP.NET Core to bind JSON requests, serialize responses, and configure common naming and syntax options.

F# in Action: A Revised Edition of Get Programming with F#
System.Text.Json is the .NET library namespace providing APIs for JSON serialization and deserialization.
- How it is used
- Serializes and deserializes JSON at application boundaries before mapping values into richer F# domain types.
- How deep it goes
- Explains API usage, raw-type mapping, validation, anonymous records, and discriminated-union limitations, but not converter implementation.
- Examples
- Uses guitar inventory JSON, RawGuitar validation, discriminated-union domain values, and anonymous-record reporting output.
- What you can do after
- Apply it via JsonSerializer to exchange JSON, validate raw records, and produce or consume richer F# domain values.

.NET in Action, Second Edition
System.Text.Json is the .NET library that provides JSON serialization, deserialization, and document-processing APIs.
- How it is used
- Uses JSON serialization and deserialization in file-processing applications and performance comparisons.
- How deep it goes
- Explains typed deserialization and practical benchmarking, but does not descend into serializer internals or configuration details.
- Examples
- Uses a jokes.json file, Joke records, command-line file processing, and comparative deserialization benchmarks.
- What you can do after
- Apply it via JsonSerializer.Deserialize<T> to convert JSON strings into typed C# objects and arrays.
