+- Use `async`/`await` patterns consistently for agent operations and workflow execution.
+- Follow .NET type-safety and dependency-injection conventions.

+- Use middleware, context providers, and orchestration components idiomatically within the .NET application model.
+- Check the latest .NET samples before introducing new APIs or workflow patterns.
