NLog.Extensions.ThisClass 1.4.12

ThisClass

Exposes class and type information as constants in the ThisClass class using source generators powered by Roslyn, inspired by ThisAssembly.

ThisClass

Add the ThisClassAttribute to generate type information for a class.

[ThisClass]
partial class Demo
{
    public Demo()
    {
        Logger.Info($"Hello from {ThisClass.FullName}"); // SampleApp.Demo
    }
}

NLog.Extensions.ThisClass

Create class loggers without using reflection.

using SomeNamespace;

namespace SampleApp.NLog
{
    ...
    namespace AnotherNamespace
    {
        using SomeOtherNamespace;
        [ClassLoggerLazy]
        partial class Demo2<T> : SomeInterface<T> where T : SomeOtherInterface
        {
            public static void SayHello()
            {
                Logger.Info("Hello");
            }

            [ClassLogger]
            internal partial class NestedClass : SomeInterface<SomeOtherInterface>
            {
            }
        }
    }
}

Looks like this behind the scenes
