PostSharp Logging (formerly PostSharp Diagnostics) is an instrumentation toolbox for .NET and .NET Core. It allows you to add extensive logging to your application in minutes and direct it to any logging framework. PostSharp Logging is easy to use but still provides all the detail you need, see parameter values, timing, and more. Much faster than hand-written code and fully customizable, you can override every single moving part. PostSharp also provides integration with your existing logging framework.
