Proper logging from a nuget library

Question

I'm developing a nuget library that is consumable from a WPF app and UWP app, and I want to use Microsoft.Extensions.Logging.Abstractions to provide users a way to plug in their logger of choice from their apps (Serilog, NLog, etc..). Therefore I've begun with this:

public static partial class FrameworkElementExtensions
{
    internal static ILogger _logger;

    public static void AttachLogger(ILogger logger) => _logger = logger;
.
.
.
}

In this case, I need to add logging to extension methods based on FrameworkElement. I feel I'm going about this the wrong way since I have a function called AttachLogger to inject a logger, and also my ILogger is not associated with a type (ex: ILogger<T> ) since I'm in a static class.

Can someone point me in the right direction? Thanks!

I don't see better way to "inject" dependency into static class with Microsoft.Extensions.Logging.Abstractions other than using dedicated method for it ( AttachLogger in your case).

Regarding generic Logger<T> , you could inject ILoggerFactory and create logger associated to your class

public static void AttachLogger(ILoggerFactory loggerFactory)
{
    _logger = loggerFactory.CreateLogger(nameof(FrameworkElementExtensions));
}
