Getting started with creating custom Build and Release tasks for VSO

You'll need to follow the steps below in order to get started:
1) Install npm for Windows if you haven't already
2) Once npm is successfully installed and available in your PATH, execute the following command to install the TFX command line package: "install -g tfx-cli"
3) Once you've installed TFX, find a folder in which you want to work to create your package, and execute a command similar to the following: "tfx build tasks create"
4) After you finish answering the questions asked by the program, you'll have a template folder for your custom build task that you can bundle up with tfx and publish to VSO.
