Explains why request DTOs should expose only allowed fields and how server-owned fields stay protected.
Updates only public mutable fields and leaves ownership, status, and audit values server-controlled.
Secures webhooks, previews, imports, and remote-file fetches with destination policy, DNS and redirect defenses, egress controls, limits, and observability.
Explains EF Core projections for API read models that need related names, counts, and summaries without loading full graphs.
Builds a read-only EF Core projection with aggregates, stable ordering, and bounded results instead of loading an entity graph.
Explain why request cancellation should flow into EF Core queries and where it does or does not help.
Explains correlation IDs across request logs, dependency calls, queues, workers, and support investigations.
Carries the ASP.NET Core request token into a bounded EF Core query while keeping cancellation separate from business rollback guarantees.
Maps a named capability to an ASP.NET Core policy and enforces it at the endpoint boundary.
Explains where secrets and tokens should live, what not to log, how rotation works, and how client storage changes risk.
Combines ThreadPool counters, repeated stack snapshots, and wait-event traces to distinguish blocked workers from CPU or dependency pressure.
Compare public and internal APIs in terms of compatibility, documentation, security, support, and evolution speed.
Compares replacement and partial-update semantics, including omitted fields, patch formats, validation, and concurrency.
Explains useful quality gates for .NET CI pipelines, including tests, analysis, security, migrations, and smoke checks.
Converts local-day boundaries to UTC once, preserving correct daylight-saving behavior and index use on stored UTC timestamps.
Fits database command timeouts into endpoint latency budgets while diagnosing slow SQL, blocking, pool pressure, and uncertain write outcomes.
Investigate and fix a race condition caused by shared mutable state in a .NET service.
Separates traffic eligibility, process recovery, and slow startup so health checks do not amplify dependency failures or restart healthy work.
Separates restricted mutation access from a stable immutable value and chooses snapshots or structural sharing deliberately.
Repairs a workflow when a remote operation may have succeeded but local state, messages, and callbacks disagree.
Explains how to inspect, fix, replay, skip, or archive dead-letter messages without repeating bad side effects.
Implements safe redaction of known sensitive keys in a dictionary before logging.
Replaces a parent query plus one status query per row with one server-side projection.
Uses metadata-driven behavior deliberately and protects reflection-dependent code when publishing with trimming or ahead-of-time compilation.
