What problem does it solve?

This Skill provides a professional framework for developing and configuring ASP.NET Core filters, ensuring controllers and actions have consistent, secure execution paths.

Core Features & Use Cases

• ActionFilter implementation and configuration to standardize pre/post action logic.
• Exception filters, model validation filters, and authorization filters to centralize cross-cutting concerns.
• Filter execution order management to reliably control the pipeline across controllers and actions.

Quick Start

1. Implement an ActionFilter or IAsyncActionFilter to add cross-cutting behavior.
2. Register the filter globally or apply it at controller or action level.
3. Create an ExceptionFilter, a CustomModelValidationFilter, and a RequireRole-based authorization filter as examples.
4. Verify the filters trigger in the expected order and handle errors consistently.
