Adoption guide

Teams staying close to first-party ASP.NET Core primitives and minimal external framework layering.

ASP.NET Core guide

Why it appears in the guide: First-party OpenAPI generation support aligned with modern ASP.NET Core hosting patterns. Trade-off: Feature customization depth may require additional conventions or complementary packages.

Compatibility metadata lists 1 target framework; 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.
