About this course

Validating your skills is the only way to verify your skills. Just like watching someone renovate a house is not the same as building a house yourself, watching tutorials isn't the same as building applications. You don't know what you can do until you do it. Practice is what separates dreamers from real-world developers.

In this course, we will take on four targeted practice projects to help you validate and verify your skills. Each project tests you on a dozen C# fundamentals. Get this course to polish and perfect your skills.

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.
