What problem does it solve?

Best practices for handling HTTP requests in ASP.NET Core 8 REST APIs covering model binding, DTO design, input binding sources, and request pipeline conventions. Trigger: When designing request DTOs, configuring model binding, handling query parameters, or processing incoming HTTP payloads in a .NET 8 API.

Core Features & Use Cases

• Enforces Request DTO naming conventions (suffix "Request") to decouple API contracts from domain models.
• Applies explicit binding sources ([FromQuery], [FromBody], [FromRoute], etc.) to improve clarity and security.
• Uses GUID route constraints to prevent naive IDs on public endpoints.
• Encourages pagination safeguards with a capped PageSize to prevent DoS via large payloads.
• Promotes null safety and default values in request DTOs for API reliability.
• Provides guidance for file uploads with proper consumes and validation patterns (D-30) when needed.
