How to register ILogger for injection in ASP.NET MVC 6

The services.AddLogging(); didn't worked for me, so I added these two statements to ConfigureServices:

services.AddSingleton<ILoggerFactory, LoggerFactory>();
services.AddSingleton(typeof(ILogger<>), typeof(Logger<>));

Now the DI container is happy and everything works.


I assumed that services.AddLogging(); was doing the right thing and registering ILogger. After looking at the source (https://github.com/aspnet/Logging/blob/d874c5726e713d3eb34938f85faf7be61aae0f2a/src/Microsoft.Framework.Logging/LoggingServiceCollectionExtensions.cs) I found that it's actually registering ILogger<>. Changing the signature of ILogger to ILogger<HomeController> makes the above example work.

public class HomeController : 
    Controller
{
    ILogger<HomeController> _logger;

    public HomeController(ILogger<HomeController> logger) 
    {
        _logger = logger;
    }

    // ...
}

Thanks to @Steve for setting me on the right track to find this.
