Adoption guide

Existing applications or integrations that already depend on Json.NET behavior and extension points.

JSON guide

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.

Published vulnerability advisories exist for this version. Read the advisory and choose a remediated version before release.

Compatibility metadata lists 9 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

Move from package metadata to a concrete selection or review workflow.
