From Zero to Hero: Logging in .NET
Learn essential logging techniques in .NET to ensure reliable applications. This course covers built-in logging, structured logging with Serilog, and advanced features for production-ready code.
About This Course
If there is one topic that every single .NET developer needs to be proficient at,
it's Logging. Logging is fundamental to every application that wants to run reliably
in production. From APIs, and web apps, to Desktop apps and mobile apps or even games,
logging should be in place to ensure you have the right information you need to know
what is going on in your system. Logging will be crucial when something inevitably
goes wrong and you need to troubleshoot it. In modern .NET, we are blessed with an
excellent built-in logger, but it is also essential to be proficient in Serilog,
the most popular logging library. In this course, Nick will translate years of valuable
logging knowledge gained in the field, working on real projects so you can follow the path of success.
