Do not hide exceptions inside fire-and-forget tasks
If work can fail, give it ownership, logging, cancellation, and a lifecycle.
Csharp
Expose a Python FastAPI AI tool as an Aspire service
Keep Python AI code behind an HTTP boundary and let Aspire wire it into the local system.
Keep model name and deployment name in config
Do not hard-code model routing decisions into application logic.
Keep vector search filters separate from semantic ranking
Use filters for eligibility and ranking for relevance instead of blending both concerns.
Measure before you optimize
Use traces, counters, profiles, and focused benchmarks before changing code for performance.
Middleware order is important
Place ASP.NET Core middleware in the order that matches routing, security, and endpoint behavior.
Nullable warnings are design feedback, not noise
Treat nullable warnings as pressure to make object state and API contracts clearer.
Pass CancellationToken through real boundaries
Thread cancellation through every expensive operation instead of dropping it mid-chain.
Prefer health checks that test dependencies deliberately
Health checks should say something useful about readiness without turning every probe into production load.
Prefer keyset pagination for deep lists
Use seek-based pagination when users move through large ordered result sets.
