+If you are an existing user of the Multilingual App Toolkit, you can continue to use it without any loss of functionality after this date. However, no further updates are planned, and new installations will not be possible after October 15, 2025.

It contains strings, either in the default language or translated into another language. The folder that contains a .resw file is typically named for the value of a language tag.

 The Multilingual App Toolkit (MAT) integrates with Microsoft Visual Studio to provide Windows apps with translation support, translation file management, and editor tools. Here are some of the value propositions of the toolkit.
 
 - Helps you manage resource changes and translation status during development.
 - Provides a UI for choosing languages based on configured translation providers.
 - Supports the localization industry-standard XLIFF file format.
 - Provides a pseudo-language engine to help identify translation issues during development.
-- Connects with the Microsoft Language Portal to easily access translated strings and terminology.
 - Connects with the Microsoft Translator for quick translation suggestions.

 You and your translator(s) can manage the status of translations in the Multilingual Editor to review uncertain translations later. You can set the status of each string in the **Properties** tab. Status values are: **New**, **Needs review**, **Translated**, **Final**, and **Signed off**. The indicator at the left of the row shows the status. When all rows show green in the Multilingual Editor, then your translation work is done.
