Testing Database Connectivity with EF Core

Ensuring database connectivity is crucial for application reliability and user experience, especially in containerized environments managed by orchestrators like Kubernetes. This guide covers two methods for testing database connectivity using EF Core: the CanConnectAsync() method for application-level checks and the ASP.NET Core health checks framework for infrastructure-level monitoring. It includes prerequisites like Docker and the Testcontainers NuGet package for setting up a SQL Server instance and provides step-by-step instructions for both methods.
