As a developer, there’s a bit more to localizing your app than just doing a right click | add French, but the Multilingual App Toolkit (MAT)—Microsoft’s app localization add-in for Visual Studio—takes the headache out of getting your apps localized and made available to a world-wide audience.
What you get with the MAT is a workflow for localization of Windows, Windows Phone, or traditional desktop apps with minimal effort. MAT includes built-in machine translation from Bing Translator as well as auto-translation with high-quality Microsoft user interface translations from the Microsoft Language Portal. The portal contains terminology and translations from already released Microsoft products: Windows, Windows Phone, Office, Xbox, Visual Studio, Dynamics, and many more—in over 100 languages. And it’s all free.
Why bother localizing your app? Because you can capture another 80% of the world’s population by adding a few additional languages, dramatically increasing your reach, downloads and revenue potential. Your app may be market-specific, but most likely has worldwide appeal so why not expand your audience?
