Adoption guide

API-heavy services that prefer explicit endpoint classes and integrated validation conventions.

ASP.NET Core guide

Why it appears in the guide: Endpoint-centric framework on ASP.NET Core with conventions for request handling and validation. Trade-off: Introduces framework-specific abstractions that must be learned and governed across teams.

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

Compatibility metadata lists 3 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.
