Linker is a really simple web-based URL shortening service. When I set out to create a Pluralsight course about my favorite built tool, Cake, I needed a .NET web application for my demos. The idea of the course was to take an existing web app and show how to use Cake to create a build and deployment pipeline for it from scratch. By the end, you'd have a Cake script that can take the application all the way from source code to running software. That idea eventually became Building and Deploying Applications with Cake, which you can read more about here.
