System.Text.Json by Microsoft

<PackageReference Include="System.Text.Json" Version="5.0.1" />

 System.Text.Json 5.0.1

Provides high-performance and low-allocating types that serialize objects to JavaScript Object Notation (JSON) text and deserialize JSON text to objects, with UTF-8 support built-in. Also provides types to read and write JSON text encoded as UTF-8, and to create an in-memory document object model (DOM), that is read-only, for random access of the JSON elements within a structured view of the data. Commonly Used Types: System.Text.Json.JsonSerializer System.Text.Json.JsonDocument System.Text.Json.JsonElement System.Text.Json.Utf8JsonWriter System.Text.Json.Utf8JsonReader When using NuGet 3.x this package requires at least version 3.4.
