Aspnet Minimal Api Openapi

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
• Use the ProblemDetailsService and StatusCodePages to get standard error responses
