Use Visual Studio Profiler, Application Insights, structured logging, and performance counters to identify bottlenecks and memory leaks.

Conduct thorough code reviews, pair programming, enforce CI/CD pipelines, and encourage automated test coverage.
How do you handle API versioning in enterprise applications?
Use versioned routes (e.g., /api/v1/), support backward compatibility, and deprecate old versions gradually with clear communication.
