Driver development in Visual Studio Component Layout WDK (Visual Studio add-on) Driver analysis tools Driver testing and deployment tools Online VS driver toolbar (build, package, sign) Debugger engine Redistributables (Developer Portal) VS driver templates KM & UM headers/libs Samples (Code Gallery) Documents (MSDN) Visual Studio Windows SDK Visual Studio Core (compiler, CRT, etc)

WDK with Windows 10 One WDK for all Windows driver development Multiple versions of the WDK can exist side-by-side on disk VS+WDK provides a consistent driver development experience across all target Windows editions Build, debug & validate Windows Universal drivers easily Running WDK tests standalone on target machine (coming at Windows 10 RTM)

Setting up VS to build Windows Universal Driver Access Driver Setting option under Driver Properties in Visual Studio Set TargetPlatform == Universal

Windows Universal driver validation tool APIValidator.exe tool Runs as a post build process for Windows Universal Drivers Also can be run on command line "C:\Program Files (x86)\Windows Kits\8.2\bin\x86\apivalidator.exe“ Flags APIs used in the driver project that aren’t part of the Windows Universal Platform

INF validator tool Purpose InfVerif.exe WinHEC 2015 4/16/2017 6:22 PM INF validator tool Purpose Validates driver package INFs and exposes errors encountered during the INF parsing process Can validate that the driver package INF will work on all Windows SKUs and in Windows Universal Driver packages InfVerif.exe Included in the WDK Runs automatically in a VS driver project Documentation on common errors and resolution available on MSDN © 2015 Microsoft Corporation.

Driver Validation Hardware Development Platform Documentation & Support Visual Studio + WDK Driver Validation

Ensuring Driver Quality Testing should begin during the driver development phase to catch issues early in development Tests bundled with the WDK allows you to assess driver quality upstream The Hardware Lab Kit (HLK) enables you to evaluate driver compatibility with Windows & assess ship readiness (covered in subsequent session)

Testing using the WDK WDK test library pre-loaded with “Device Fundamentals” tests Provides the ability to run the same test on Windows PC, tablets and phones Tests can be executed on the target device by either: Using WDK Test Explorer in VS Running the test standalone using test package(s) that includes a test and all support components needed to run the test and deliver results using easy to read logs
