Adoption guide

Assess this package against its supported frameworks, license, maintenance signals and dependency graph before making it a project standard.

Compatibility metadata lists 4 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.
