IProblemDetailsService

As explained in ASP.NET Core in Action, 3e

IProblemDetailsService is an ASP.NET Core service interface that generates Problem Details responses for errors.

IProblemDetailsService generates Problem Details responses for errors in ASP.NET Core applications. Register it with AddProblemDetails() so exception-handling middleware can produce an error response without a dedicated error endpoint. section 5.3.3

Configure automatic exception responses

Register the service, configure UseExceptionHandler() without a path, and throw an exception from an endpoint. ExceptionHandlerMiddleware then uses IProblemDetailsService to generate the response.

How ASP.NET Core in Action, 3e covers it

How deep it goes
Explains service registration and middleware behavior, including exception handling and empty error-status responses.
Examples
Demonstrates a throwing endpoint and a NotFound response configured through minimal API middleware.
What it assumes
Assumes a minimal API application and introduces the required dependency-injection registration for the service.
What you can do after
Operate automatic Problem Details responses by registering the service and configuring exception or status-code middleware.
How it connects
Connects Problem Details with dependency injection, ExceptionHandlerMiddleware, DeveloperExceptionPageMiddleware, and StatusCodePagesMiddleware.
