Map ASP.NET Core ProblemDetails and FluentValidation field errors onto Angular Reactive Forms — FormGroup patterns, setErrors, submit UX, interceptors, and tests. Not a FluentValidation server tutorial.

Angular Signals for API-driven apps — load state from ASP.NET Core, computed UI flags, RxJS interop, and when Signals beat BehaviorSubject for SPA state.

OnPush rerenders a component when an input identity changes, an event fires, or a signal updates. Mutating an object in place does not. This is the change-detection page, not the signals guide and not the interview list.

Host Angular SSR or prerender with an ASP.NET Core API — process layout, cookies and TransferState, MapFallbackToFile vs API routes, App Service/container deploy sketch, and when SSR is not worth it for SaaS shells.

Angular state management decision for ASP.NET Core backends — local Signals, SignalStore for entity CRUD, and when classic NgRx Effects still win. Complements the Signals how-to; does not rewrite it.

Which RxJS map to use when Angular calls an ASP.NET Core API: switchMap for search, exhaustMap for submit, concatMap when order matters. The wrong one drops or doubles the request.
