Create C# Minimal API

When to Use

• When initializing the C# migration project
• When adding the next C# endpoint
• When introducing DTOs or services to support parity
• When wiring weather.json data into the C# application

Procedure

1. Confirm the specific endpoint or scope to implement.
2. Read the Python source and related tests first.
3. Review the checklist in project-checklist.
4. Generate or edit only the minimum required C# files.
5. Stop after a small milestone and suggest the narrowest validation step.

Rules

• Use ASP.NET Core Minimal APIs.
• Keep changes incremental and reviewable.
• Prefer System.Text.Json for JSON handling.
• Avoid broad rewrites when only one endpoint is being added.
• Preserve response behavior unless the task explicitly allows change.

Output

• Files created or edited
• Scope implemented
• Remaining TODOs
• Recommended validation command
