ASP.NET Core in Action, 3e
IResult is an ASP.NET Core interface representing the result produced by an HTTP endpoint for an HTTP response.
- How it is used
- Uses IResult to let minimal API endpoints return accurate HTTP status codes and customized responses.
- How deep it goes
- Explains return conventions, ExecuteAsync, helper types, status codes, and manual-response alternatives without implementing a custom result.
- Examples
- Demonstrates fruit lookup and creation, not-found and bad-request responses, Problem Details helpers, files, binary data, streams, and a manual teapot response.
- What you can do after
- Apply it via Results and TypedResults to build minimal API endpoints with deliberate success and error responses.
.NET in Action, Second Edition
IResult is an ASP.NET Core interface representing the result of executing an HTTP endpoint.
- How it is used
- Shapes endpoint handlers that return successful responses or expected failures without throwing exceptions.
- How deep it goes
- Defines the shared return type through focused endpoint examples, but does not detail IResult internals.
- Examples
- Uses ASCII-art text, invalid fonts, barcode images, Results.Content, Results.NotFound, and Results.File.
- What you can do after
- Apply it via ASP.NET Core endpoint handlers to select content, not-found, or file responses from operation results.
