Download the Multilingual App Toolkit for Windows and Windows Phone. One of the exciting things about Windows Phone development is the extraordinary reach that Windows Phone apps have across the world. Windows Phone apps can be made available in 191 markets across the world and we've seen great adoption of Windows Phone in many different languages. In fact, the Windows Phone app market in China is bigger than it is in the US. This means that for Windows Phone developers to reach the largest possible audience for their application, they need to adopt some localization best practices. This is where the Multilingual App Toolkit (MAT) comes in. Using MAT, developers can access machine translation through the Microsoft Language Portal for their application resources at absolutely no cost. If you prefer a different source for machine translation, MAT allows support for 3rd part translation providers. For scenarios where you might prefer human translation (or translation verification), MAT has the ability to import and export multiple XLIFF files. Watch the video for all the details and make sure you utilize the power of the Multilingual App Toolkit when you're looking to expand the market for your application.
