Authoring VS Team Services extension with Build/Release Tasks

This post provides a step-by-step guide on authoring and packaging Visual Studio Team Services (VSTS) extensions that include custom build and release tasks. It details modifying existing tasks (e.g., Azure PowerShell task to support inline scripts), updating task metadata (task.json), creating extension manifests (vss-extension.json), and packaging/publishing extensions to the VSTS marketplace. The process involves modifying task execution logic (e.g., PowerShell scripts), defining task inputs and UI elements in task.json, and referencing these tasks within the extension manifest.
