Command-line interfaces (CLI) can be very powerful. The same is true in the .NET world. So let's get comfortable with creating, running, and testing applications using the command-line interface.

Whether you're new to .NET or have been using .NET with Visual Studio, this session will help you get up-to-speed in this powerful environment.
