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.
Processes a large import in chunks with fresh DbContexts, idempotent keys, cancellation, and bounded tracker growth.
Builds a story about improving code quality incrementally while still delivering product value.
Builds a story about improving team workflow with lightweight, useful process changes.
Explains how to respond to a production incident caused by a bad release.
Verifies the exact request bytes, rejects stale signatures, deduplicates event ids, and queues processing durably.
Explains how to inspect EF Core generated SQL and connect LINQ shape to database execution behavior.
Uses WebApplicationFactory with test-only authentication and isolated dependencies to exercise the real ASP.NET Core pipeline.
Uses the real ASP.NET Core pipeline while replacing only environment-specific boundaries deliberately.
