Json.NET (Newtonsoft.Json) is the most popular high-performance JSON framework for .NET, providing serialization, LINQ to JSON, JSON Path queries, and XML conversion. It has over a billion NuGet downloads and supports a wide range of .NET platforms.
Use cases
- serialize .NET objects to JSON
- deserialize JSON into C# classes
- parse and query JSON without a class
- query JSON with JSON Path
- convert between JSON and XML
- read and write indented readable JSON
When to choose
- you need battle-tested JSON handling in .NET with broad platform support
- your JSON maps closely to .NET classes but you also need flexible manual parsing
- you need JSON Path querying or XML conversion alongside serialization
When to avoid
- you are on modern .NET and prefer the built-in System.Text.Json for performance and no extra dependency
- you need a JSON Schema validator, which is a separate commercial product (Json.NET Schema)
