Interaction with app

Prerequisites

• Microsoft Teams is installed and you have an account (not a guest account)
• .NET 6.0 SDK.

      # determine dotnet version
      dotnet --version

• dev tunnel or ngrok latest version or equivalent tunneling solution
• M365 developer account or access to a Teams account with the appropriate permissions to install an app.
• Teams Toolkit for Visual Studio

Run the app (Using Teams Toolkit for Visual Studio)

The simplest way to run this sample in Teams is to use Teams Toolkit for Visual Studio.

1. Install Visual Studio 2022 Version 17.10 Preview 4 or higher Visual Studio
2. Install Teams Toolkit for Visual Studio Teams Toolkit extension
3. In the debug dropdown menu of Visual Studio, select default startup project > Microsoft Teams (browser)
4. In Visual Studio, right-click your TeamsApp project and Select Teams Toolkit > Prepare Teams App Dependencies
5. Using the extension, sign in with your Microsoft 365 account where you have permissions to upload custom apps.
6. Select Debug > Start Debugging or F5 to run the menu in Visual Studio.
7. In the browser that launches, select the Add button to install the app to Teams.

If you do not have permission to upload custom apps (sideloading), Teams Toolkit will recommend creating and using a Microsoft 365 Developer Program account - a free program to get your own dev environment sandbox that includes Teams.

Setup.

Note these instructions are for running the sample on your local machine, the tunnelling solution is required because the Teams service needs to call into the bot.

1. Run ngrok - point to port 3978

   ngrok http 3978 --host-header="localhost:3978"

   Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:

   devtunnel host -p 3978 --allow-anonymous

2. Clone the repository

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

3. Open the code in Visual Studio

   • File -> Open -> Project/Solution
   • Navigate to folder where repository is cloned then samples/meetings-live-caption/csharp/MeetingLiveCaption.sln

4. Run the bot from Visual Studio:

   • Press F5 to run the project

5. Modify the manifest.json in the /appPackage folder and replace the following details:

   • <<AppId>> with any GUID id value.
   • <<App-Domain>> with base Url domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your domain-name will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.

6. Zip the contents of appPackage folder into a manifest.zip, and use the manifest.zip to deploy in app store or add to Teams using step 6.

7. Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")

   • Go to Microsoft Teams and then go to side panel, select Apps
   • Choose Manage your apps -> Upload an app -> Upload a custom App
   • Go to your project directory, the ./appPackage folder, select the zip folder, and choose Open.
   • Select Add in the pop-up dialog box. Your app is uploaded to Teams.
