This article provides a solid guide to implementing health checks in .NET 8, but it could benefit from covering additional customization options for complex scenarios. For example, health checks can be tailored to monitor specific application dependencies like databases, message queues, or external APIs, which is crucial for microservices. Discussing response caching for health check endpoints could also be valuable, as it helps optimize performance by reducing repeated checks on heavily requested endpoints.

Great resource for getting started—these additions would make it even more robust!
