Remote debugging is implemented using the Windows Web Services API. The Windows
        Web Services API is a building block that applications, such as the remote debugger,
        can use to communicate over the network. This API is already included in Windows
        7, Windows Server 2008 R2 and later operating systems. For Windows Server 2008 
        (pre-R2), the Visual Studio Remote Tools setup will automatically install the API.
