Compares vendor-neutral OpenTelemetry concepts with Application Insights usage for .NET production services.
Compares Redis pub/sub with durable queues when broadcasting cache invalidation or refresh events.
Explains how roles group permissions while API policies enforce specific capabilities and resource rules.

Choose between ConcurrentDictionary and explicit locks when managing concurrent in-memory data.
Explains how environment configuration drift causes deployment bugs and how to reduce it.

Compare endpoint styles in real services, including organization, conventions, testing, filters, and OpenAPI behavior.
Explains sampling, high-cardinality labels, retention, cost, and keeping enough signal for incident diagnosis.

Explains deployment markers, version telemetry, feature-flag state, commit traceability, and incident diagnosis after releases.
Decide how to handle CPU-heavy work in an API without damaging request throughput or making the system unreliable.
Applies CQRS proportionally, separating model responsibilities without assuming separate databases, messaging, or event sourcing.
Creates and disposes explicit service scopes for hosted, queued, and parallel work without sharing scoped dependencies across operations.
Explains what belongs in runbooks, how on-call handoff preserves context, and how operational docs stay useful.
Explain why awaiting while holding synchronization resources can create deadlocks, contention, or stalled workflows.
Debugs ASP.NET Core authentication challenges and authorization forbids across schemes, token validation, policies, claims, tenants, and resource checks.
