dotnet-scaffold-file-authorization-handler

Directory-based file authorization in .NET is implemented by scaffolding an internal sealed class inheriting UmbrellaFileAuthorizationHandler for a specific DirectoryName, with cancellation checks and validation in AuthorizeAsync. The handler is then registered via dependency injection.

Scaffolding a file authorization handler generates a sealed class inheriting UmbrellaFileAuthorizationHandler, which you register in the dependency injection container as IUmbrellaFileAuthorizationHandler to authorize file system access.

The AuthorizeAsync method in UmbrellaFileAuthorizationHandler performs cancellation checks, input validation, and safe directory-based authorization logic to decouple access control from the file handler workflow.

Yes, dependency injection manages file access control in the Umbrella Core.Logic file system by registering your scaffolded handler as IUmbrellaFileAuthorizationHandler, binding authorization to the directory-specific workflow.

A dedicated file authorization handler is needed when decoupling directory-based access control from file handling logic in Umbrella's Core.Logic, ensuring secure permissions through cancellation checks and input validation.

Scaffolding a dedicated handler decouples access control from the file handler, applying secure directory-based permissions via IUmbrellaFileAuthorizationHandler registration rather than scattering inline authorization checks.
