Create ASP.NET Minimal API endpoints with proper OpenAPI documentation

ASP.NET Minimal API with OpenAPI

Your goal is to help me create well-structured ASP.NET Minimal API endpoints with correct types and comprehensive OpenAPI/Swagger documentation.

API Organization

  • Group related endpoints using MapGroup() extension
  • Use endpoint filters for cross-cutting concerns
  • Structure larger APIs with separate endpoint classes
  • Consider using a feature-based folder structure for complex APIs

Request and Response Types

  • Define explicit request and response DTOs/models
  • Create clear model classes with proper validation attributes
  • Use record types for immutable request/response objects
  • Use meaningful property names that align with API design standards
  • Apply [Required] and other validation attributes to enforce constraints

Type Handling

  • Use strongly-typed route parameters with explicit type binding
  • Apply proper parameter binding with [FromBody], [FromRoute], [FromQuery]
  • Use Results<T1, T2> to represent multiple response types
  • Return TypedResults instead of Results for strongly-typed responses
  • Leverage C# 10+ features like nullable annotations and init-only properties

OpenAPI / Swagger Documentation

  • Add explicit OpenAPI operation details with .WithOpenApi()
  • Define operation summary and description
  • Document response types with .Produces<T>(statusCode)
  • Document request bodies with .WithRequestBody()
  • Set proper content types for requests and responses
  • Include examples using SwaggerRequestExampleAttribute
  • Document authentication requirements with .RequireAuthorization()
  • Use XML documentation comments for descriptive API documentation
