Teams App Localization

This sample illustrates how to implement Localization for Microsoft Teams apps.

Prerequisites

Verify you have the right account for building Teams apps and install some recommended development tools.

• You need a Teams account that allows custom app sideloading.
• .NET Core SDK version 3.1
• ngrok or equivalent tunnelling solution

1. Clone the repository

   git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

2. If you are using Visual Studio

• Launch Visual Studio
• File -> Open -> Project/Solution
• Navigate to app-localization\csharp folder
• Select Localization.csproj file

3. Run ngrok - point to port 3978

   ngrok http --host-header=localhost

4. This step is related to Microsoft Teams app manifest

   • Edit the manifest.json contained in the Manifest folder to replace your Microsoft App Id (that was created when you registered your bot earlier) everywhere you see the place holder string <<YOUR-MICROSOFT-APP-ID>> (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
   • Provide ngrok Url (turnnelling Url) in manifest.json for contentUrl in case of tabs and for messaging endpoint in case of bots if enabled.
   • Zip up the contents of the teamsAppManifest folder to create a manifest.zip
   • Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")

5. Run your app, either from Visual Studio with F5 or using dotnet run in the appropriate folder.

Interacting with the app in Teams

In Teams, Once the app is successfully installed, you can interact with tab and bot in your preferred language.

To change language in Teams

To change the language in Microsoft Teams, please click your profile picture at the top of the app, then select Settings -> General and go to the Language section. Choose the preferred language and restart to apply the change. This sample supports en-US, fr-CA, hi-IN and es-MX.

1. Installation: You should see your app installation screen content in selected language.

2. Bot: send any message to see localized

3. Tab: click on tab to see localized info.
