How would you design a self-healing system in .NET Core?

A self-healing system in .NET Core is designed to automatically detect failures (like service crashes, slow responses, or dependency failures) and recover using techniques such as retry policies, health checks, circuit breakers, auto-scaling, and orchestration tools without manual intervention.

A self-healing architecture ensures that an application can:

In a .NET Core ecosystem, self-healing is achieved using multiple layers:

🔷 1. Health Checks (Failure Detection Layer)

.NET Core provides built-in health check middleware:
