How do I inject a logger into MediatR command handlers?

Question

I am attempting to debug a web application that uses the Mediator design pattern via the MediatR package. I have a logger in the web API controller, but because of the nature of the design pattern, I don't know how I can pass that logger from the controller to the command, and then into the command handler. I'm all but certain this is down to inexperience on my part - what am I missing here?

Answer 1

In your handler(s), grab an instance of ILogger from the DI container, assuming you’ve added logging.

E.g. https://github.com/microsoft/AspNetCore-React-WebApp/blob/main/service/Microsoft.DSX.ProjectTemplate.Data/Services/EmailService.cs

Does this help?
