Open API Specification

If not asked otherwise, add Open API Specification:

• Add NuGet packages:
  • Microsoft.AspNetCore.OpenApi
  • Swashbuckle.AspNetCore.SwaggerUI
  • Microsoft.Extensions.ApiDescription.Server Add Open API services to DI (builder.Services.AddOpenApi();)
  • Add Swagger UI middleware (app.UseSwaggerUI(options => options.SwaggerEndpoint("/openapi/v1.json", "v1"));)
• Add entry to PropertyGroup in .csproj to generate Open API specification on build (<OpenApiDocumentsDirectory>.</OpenApiDocumentsDirectory>)

This will generate an Open API specification file (<project-name>.json) in the project directory on build

Always add proper Open API-related metadata (e.g. .Produces(), .WithDescription(), .WithTags(), etc.) to the endpoints to ensure a good API documentation and client generation experience.

CORS

If not asked otherwise, add CORS with allow any origin, header, and method.

Aspire Integration

If the web API is part of an Aspire application:

• Ensure that service defaults are added to DI in the web API (builder.AddServiceDefaults())
• Ensure that the web API it is properly integrated with the AppHost

If you are unsure, research in the Aspire documentation at https://aspire.dev/llms.txt.
