Minimal APIs are Microsoft's recommended approach for new ASP.NET Core HTTP API projects. They provide a lightweight, lambda-based programming model with first-class OpenAPI support, endpoint filters for cross-cutting concerns, and route groups for organization at scale.

Route Groups

Route groups organize related endpoints under a shared prefix, applying common configuration (filters, metadata, authorization) once. They replace repetitive chaining of MapGet/MapPost with shared prefixes.
