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.
Explains DbContext lifetime and unit-of-work boundaries with practical .NET data-access examples and production trade-offs.
Explain how Task.WhenAll behaves when one or more tasks fail and how to inspect failures safely.
Covers using managed identity and Microsoft Entra authentication for Azure SQL access from a .NET API.
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.
Covers deployment logs, startup failures, runtime stack, app settings, missing files, Key Vault references, and post-deployment diagnosis.
Turns LOH theory into an API investigation around large payloads, buffers, serialization, and concurrency.
Explains safe migration strategy for Azure-hosted .NET APIs, including expand-contract changes, locking risk, rollback, and deployment order.
Gives a practical incident flow for memory growth using metrics, traffic correlation, heap evidence, and safe mitigation.
Explains same-artifact promotion, environment-specific configuration, approvals, smoke testing, drift detection, and production traceability.
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.
Describes lazy iterator execution, state-machine behavior, early termination, resource disposal, and repeat-enumeration consequences.
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.
Chooses immutable values and controlled mutable entities based on identity, concurrency, invariants, allocation cost, and update semantics.
Validates size and signature, writes under a generated storage key, and keeps untrusted files outside the public web root.
