Note The Windows Driver Kit (WDK) 8 includes additional debugging tools: WSDDebug_client.exe and WSDDebug_host.exe. If you open a Visual Studio Command Prompt window, you can find these tools in the %WindowsSdkDir%\bin\<arch> directory. (These tools are also included in the Microsoft Windows SDK.)
These tools are a soft device and client that you can use to troubleshoot devices or applications. For more information about WSDDebug_client and WSDDebug_host, see the Web Services on Devices section of the Windows SDK.
