About this course

AppSettings are powerful ... and complicated! Misconfigured settings can leave your app vulnerable.

Not knowing how to configure AppSettings means you are making things harder for yourself. It used to be we had one place to put settings: the app.config/web.config file. Now with .NET Core, we get five different settings locations by default, plus there are many more that are available to us. But when you know what you are doing; you can have the confidence to configure your app in a way that is powerful, efficient, and safe.

This course dives deep into how to configure your application settings in the way that works best for you!

Hi, I'm Tim Corey.

I learned software development the hard way, with lots of dead-ends, confusion, and knowledge gaps. I kept thinking, “It shouldn't be this hard!” Now I teach students how to think and code like professional developers. My goal is to make it easier for you to become a developer.
