Adoption guide

A verified publisher signal is available. Assess fit from the package's supported frameworks, license and dependency graph rather than popularity alone.

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

Compatibility metadata lists 4 target frameworks; confirm the exact target used by your application.

The published metadata declares 18 direct dependency entries across framework groups. Inspect the resolved dependency graph for your target framework.

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.
