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)

30. 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)

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

32. 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

33. 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

Build <-> Debug driver Windows Universal Driver using Visual Studio
Test Driver using WDK Test
Replace non universal APIs
Submit for signing
Install Visual Studio 2015 & WDK
Pick a Windows Universal Driver template or sample
Select driver architecture (ARM, x86, x64)
Add your code, headers, libs, etc
Compile / debug / etc.
Replace non Universal APIs flagged by APIValidator.exe
Deploy to target machine (dev board)
Run available tests

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

36. 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)

37. 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
