Throughout the development of our microservices, we heavily leveraged dependency injection. As part of a .NET web application's startup process, you register the individual types that should be part of the inversion of control (IoC) container. Individual classes inject their dependencies as interfaces in their constructor arguments. This allows different concrete implementations to be used depending on the context. For example, an interface for a telemetry client may be utilized throughout the codebase. The concrete implementation in the live-service sends actual telemetry data to a remote endpoint. A mocked implementation is used in unit tests to validate the correct event would be sent at the appropriate time.
