Windows and Visual Studio are collaborating to create a world-class environment for driver development.

www.buildwindows.com

Agenda• Why modern driver development?• Getting started/migrating to Visual Studio• Focus on driver quality• Simplifying common driver development tasks

Key take-away• Understand Microsoft investments for driver

development and how to use them to create great drivers more quickly

www.buildwindows.com

Primary goals for Windows 8

• Make developers more productive• Integrate driver tools into the modern Visual Studio

environment• Find defects early• Move quality “upstream” in the development process• Integrate quality tools and tests into Visual Studio

• Ease creation of more reliable, better-performing drivers• Enhance driver development frameworks• Simplify common driver development tasks

Driver development in Visual Studio “11”

• Visual Studio “11” is the recommended development environment for building Windows 8 drivers

• Driver-specific functionality is delivered via a Windows Driver Kit (WDK) add-on pack to Visual Studio

• Copies of Visual Studio “11” Ultimate and the WDK are on the USB stick you received with your conference materials

WDK (Visual Studio add-on)

Getting started

• Get going quickly• New Visual Studio templates provided for networking,

storage, printing, WDF (KMDF and UMDF) and WDM drivers

• New tool automates migration of existing Windows 7 driver projects

• Write less code• The Windows Driver Framework (WDF) has new support

for power management, kernel-mode DMA and user-mode hardware access

Driving quality “upstream”Tools• Compiler enhancements ease driver development• C++ is a “first class citizen” for creating drivers• New “/kernel” switch catches illegal driver code at

compile-time• Integrated analysis tools find bugs early• Static Driver Verifier (SDV)• Code Analysis (was PREfast/PFD)

Simplifying common tasksScenario focus• “Easily run tests” automates build-debug cycle for

developers• Automated driver build, packaging, signing and

deployment• Test library pre-loaded with “Device Fundamentals” tests• Remote machine provisioning and integrated kernel

debugging• “Easily write tests” simplifies creation of new driver

tests• Create new driver tests with Visual Studio templates

“Release notes”

• Timing• Get started now with driver development using Visual

Studio!• Visual Studio “Go Live” licensing takes effect at beta

• Visual Studio in “build labs”• Version-control tool scenarios will be documented at beta

• Operating System Targeting• Windows 8, Windows 7, Windows Vista and Windows

Server 2008 (SP2 and R2) are supported

Summary

• Make developers more productive• Try it in Hands On Lab # 721, “Experiencing Windows

Driver Kit integration with Visual Studio”• Find defects early• Learn more at Session #239, “Moving driver quality

upstream with WDK Driver Verification and Test Tools”• Ease creation of more reliable, better performing

drivers• Ask the experts at Chalk Talk #907, “Inside the Windows

8 driver developer workflow”

Visual Studio licensing

• Visual Studio is licensed per-user, not per-installation

• MSDN licensees receive all versions of Visual Studio shipped while their subscription is active

• More information for Enterprises here• Start-ups and smaller businesses may be eligible

for BizSpark or the Microsoft Partner Network (MPN)

• Academic institutions (incl. students) can take advantage of DreamSpark
