Unable to resolve ILogger from Microsoft.Extensions.Logging

Question

var services = new ServiceCollection()
                .AddLogging(logging => logging.Add         


        

Answer 1

In .NET Core, ILogger is automatically registered for you. As ILogger inherits from ILogger, you can request an instance of ILogger from the IServiceProvider.

For example: services.AddSingleton(svc => svc.GetRequiredService>());

Note that this will return an ILogger wherever you've got a non-generic ILogger constructor parameter so if you need more than one, look into creating it specifically for that instance by using the AddSingleton (or transient/or scoped) implementationFactory override.
