Propagates request cancellation through async dependencies while keeping committed side effects and timeout policy explicit.
Covers App Service app settings, environment-specific configuration, restarts, slot settings, and avoiding hard-coded production values.
Explain how Task.WhenAll behaves when one or more tasks fail and how to inspect failures safely.
Covers allocation rate, collection frequency, latency symptoms, and safe production steps for GC-heavy services.
Uses file upload processing to practice bounded memory, stream ownership, temporary files, and retained buffers.
Covers chunking, bounded concurrency, scoped dependencies, progress, retries, and avoiding full-dataset memory spikes.
Explains health endpoints, readiness versus liveness, warm-up, dependency checks, and safe App Service health behavior.
Covers queue-backed work, idempotency, retries, visibility timeout, poison messages, progress tracking, and choosing Storage Queues or Service Bus.
Turns LOH theory into an API investigation around large payloads, buffers, serialization, and concurrency.
Gives a practical incident flow for memory growth using metrics, traffic correlation, heap evidence, and safe mitigation.
Frames allocation reduction as measurement-driven API work rather than premature micro-optimization.
Explains a practical Git workflow for a .NET team using branches, pull requests, code review, and protected main branches.
Explains correlation IDs, distributed tracing, dependency telemetry, message boundaries, and logs across App Service, queues, and downstream APIs.
Keeps HttpContext inside the active request, avoids concurrent access, and copies only immutable data needed by later work.
Compare synchronous enumeration with async streaming and explain when IAsyncEnumerable helps with large or delayed data.
Explains how IHttpClientFactory separates short-lived clients from pooled handlers and how concurrency, DNS, resilience, and DI lifetimes still require judgment.
Validates size and signature, writes under a generated storage key, and keeps untrusted files outside the public web root.
Explains upload UX, API boundaries, validation, progress, storage, scanning, failure handling, and safe download behavior.
Validates a bounded command set completely before applying all updates in one SaveChanges transaction.
Builds a bounded readiness check for one required dependency while keeping liveness independent and responses non-sensitive.
Stores an idempotency key, request hash, and response in the same transaction as the created resource.
Implements descending keyset pagination in LINQ using a compound timestamp-and-id cursor.
Explains debounce, cancellation, stale-response protection, loading indicators, and backend query safety for search UI.
Explains stable EF Core pagination using cursor predicates, deterministic ordering, and index-aligned queries.
