How do I read the request body multiple times in middleware?

By default, the request body is a forward-only stream. You must call context.Request.EnableBuffering() at the start of your middleware to allow the stream to be seekable for multiple reads.

Why is middleware ordering important in ASP.NET Core?

The order determines the sequence in which requests are processed and responses are generated. Incorrect placement can lead to security vulnerabilities, such as placing Authorization before Routing, which allows requests to bypass permission checks.

When should I use IMiddleware instead of the convention-based pattern?

Use IMiddleware when your middleware requires scoped services from the Dependency Injection container. IMiddleware is resolved per-request, whereas convention-based middleware is typically a singleton.

Can middleware stop a request from reaching the controller?

Yes, middleware can 'short-circuit' the pipeline by returning a response directly (e.g., setting a 401 Unauthorized status) and choosing not to call the 'next' delegate.

API開発

Builds robust ASP.NET Core middleware pipelines with expert guidance on ordering, custom implementations, and error handling.

This skill provides comprehensive architectural guidance for developing and orchestrating ASP.NET Core middleware. It helps developers avoid common pitfalls in request pipeline ordering, implement custom middleware using both convention-based and factory patterns (IMiddleware), and handle advanced scenarios like request buffering, response manipulation, and global exception handling. Whether you are building security gates, logging utilities, or performance monitors, this skill ensures your HTTP pipeline is efficient, secure, and maintainable according to modern .NET best practices.
