FAST-FORWARD THE LEARNING CURVE.
Maximize your team’s existing expertise. Familiar yet powerful tools—like Microsoft® Visual Studio® and the .NET
programming model—allow your team to focus project hours on building the next generation of smart, connected
devices. Plus, componentized and fully confi gured platforms in Windows® Embedded can help save your team more
unnecessary effort—so more time can be spent differentiating your fi nal product, or simply bringing it to market
faster. Learn more about how to fast-forward device development at: windowsembedded.com/fastforward
