diff: ## Overview
  -The WinRM - IIS Web App Deployment task is used to deploy a web application, and the underlying technology used by the task is [Web Deploy](http://www.iis.net/downloads/microsoft/web-deploy). Web Deploy packages the web application content, configuration and any other artifacts like registry, GAC assemblies etc. that can be used deployment. If the package needs to be redeployed to a different environment, configuration values within the package can be parameterized during deployment without requiring modifications to the packages themselves. Web deploy works with IIS 7, IIS 7.5, IIS 8, and IIS 8.5.

  The task runs on the automation agent machine, and connects to the target machine(s) using [Windows Remote Management][1] (WinRM), and launches a bootstrapping executable program (VisualStudioRemoteDeployer.exe) on the target machine(s), and the bootstrap executable invokes the PowerShell scripts to locate the AppCmd.exe on the machine, and creates or updates the website and the application pool using the AppCmd.exe. As the execution happens within the target machine(s), it is important to have the pre-requisites described below, installed properly on the target machine(s).
