Adoption guide
Existing applications or integrations that already depend on Json.NET behavior and extension points.
Why it appears in the guide: A long-established JSON library with a broad converter and compatibility ecosystem. Trade-off: It adds a package dependency where System.Text.Json may already be available in the runtime.
This version is marked prerelease. Validate its API and upgrade path before production use.
Compatibility metadata lists 8 target frameworks; confirm the exact target used by your application.
How to read this guidance
Sources: published NuGet v3 registry metadata and explicit NuBrowse editorial guides. Refresh: package metadata is refreshed from NuGet when the page loads. Limit: this is not a security, legal or compatibility guarantee; validate the selected version in your project.
Useful next steps
