You will learn how to set up your Visual Studio environment to enable extension development for VSTS/TFS. Developing a build and release task and publishing and using it in build/release will give you the capability to add your own functional components to TFS build and release management.
Prerequisites: You have Visual Studio 2015 and VSTS/TFS. In your Visual Studio environment, npm is available. If not, get npm from https://www.npmjs.com/get-npm and set up Node.js and npm.
