This skill provides expert guidance for implementing robust file upload functionality within ASP.NET Core Minimal APIs. It covers essential patterns for handling IFormFile parameters, configuring dual-layer file size limits across Kestrel and FormOptions, and managing .NET 8's automatic antiforgery validation. Beyond basic implementation, the skill emphasizes security through magic byte verification and offers advanced techniques for streaming large files using MultipartReader to prevent memory buffering, ensuring your backend services are both secure and scalable.
