Even though using Dependency Injection is a better solution, but in some cases you have to use static methods (like in Extension Methods).

For those cases you can add a static property to your static class and initialize it in your ConfigureServices method.

For example:

public static class EnumExtentions
{
    static public IStringLocalizerFactory StringLocalizerFactory { set; get; }

    public static string GetDisplayName(this Enum e)
    {
        var resourceManager = StringLocalizerFactory.Create(e.GetType());
        var key = e.ToString();
        var resourceDisplayName = resourceManager.GetString(key);

        return resourceDisplayName;
    }
}

and in your ConfigureServices:

EnumExtentions.StringLocalizerFactory = services.BuildServiceProvider().GetService();
