Multilingual App Toolkit includes an extension for Visual Studio that enables simpler translation workflows by focusing on the following areas:

Integration with Visual Studio IDE lets you add and manage translation files within a project solution, by using standard Visual Studio menus and dialogs.

Pseudo language integration gives you ‘in house’ testing of localized apps by identifying localization issues during development. These issues can include hardcoded, concatenated, or truncated strings, and visual issues that arise when working with different languages. Pseudo translations are stored in the localization industry standard XLIFF file format, and you can edit them just like any other language translation. This gives you granular control over pseudo translation testing.

Microsoft Language Portal integration provides terminology and user-interface translations from actual Microsoft products through the Microsoft Terminology Service API (requires active internet connection).

Machine Translator integration provides suggestions via the integrated Microsoft Translator Service (requires active internet connection). Integration with the Microsoft Translator Service allows for instant visualization and testing across multiple languages without the assistance of a human translator.

Translation file export & import roundtrip functionality allows you to send and receive resources via XLIFF files to individuals or a translator service.

Use the dedicated localization editor to easily edit translated strings. Get translations and suggestions quickly via the integrated Microsoft Language Portal and the Microsoft Translator services (requires active Internet connection). The editor also allows you to quickly edit data stored in XLIFF files by adjusting pseudo and actual translations.
