Adoption guide

New .NET applications that target modern runtimes and can use its supported serializer model.

JSON guide
Why it appears in the guide: The JSON stack built into modern .NET, with source generation and a low-allocation design. Trade-off: Check behavior differences before migrating Newtonsoft.Json attributes, converters or reference handling.

This version is marked prerelease. Validate its API and upgrade path before production use.

NuGet marks this package as deprecated. Review the publisher's migration guidance before adopting it.

No SPDX license expression is published. Review the license text and your organisation's policy before redistribution.

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.
