Adoption guide

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.
