Try it yourself - experience the App in your Microsoft Teams client

Please find below demo manifest which is deployed on Microsoft Azure and you can try it yourself by uploading the app manifest (.zip file link below) to your teams and/or as a personal app. (Sideloading must be enabled for your tenant, see steps here).

Prerequisites

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 Dev Tunnels > Create A Tunnel (set authentication type to Public) or select an existing public dev tunnel.
  4. In the debug dropdown menu of Visual Studio, select default startup project > Microsoft Teams (browser)
  5. In Visual Studio, right-click your TeamsApp project and Select Teams Toolkit > Prepare Teams App Dependencies
  6. Using the extension, sign in with your Microsoft 365 account where you have permissions to upload custom apps.
  7. Select Debug > Start Debugging or F5 to run the menu in Visual Studio.
  8. 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

  1. Register a new application in the Microsoft Entra ID – App Registrations portal.

    NOTE: When you create your app registration, you will create an App ID and App password - make sure you keep these for later.

  2. Setup NGROK

  • 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
    
  1. Setup for code
  • Clone the repository

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

    In a terminal, navigate to samples/meeting-live-coding-interview/csharp

    # change into project folder
    cd # MeetingLiveCoding
    
    Run the app from a terminal or from Visual Studio, choose option A or B.
    
    A) From a terminal
    
    ```bash
    # run the app
    dotnet run
    

    B) Or from Visual Studio

    • Launch Visual Studio
    • File -> Open -> Project/Solution
    • Navigate to MeetingLiveCoding folder
    • Select MeetingLiveCoding.csproj file
    • Press F5 to run the project
  • Inside ClientApp folder execute the below command.

    # npx @fluidframework/azure-local-service@latest
    
  1. Setup Manifest for Teams
  • This step is specific to Teams.

    • Edit the manifest.json contained in the ./appPackage folder to replace your Microsoft App Id (that was created when you registered your app registration earlier) everywhere you see the place holder string {{Microsoft-App-Id}} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)
    • Edit the manifest.json for validDomains and replace {{domain-name}} with base Url of your 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.
    • Zip up the contents of the appPackage folder to create a manifest.zip (Make sure that zip file does not contains any subfolder otherwise you will get error while uploading your .zip package)
  • Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")

    • Go to Microsoft Teams. From the lower left corner, select Apps
    • From the lower left corner, choose 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.

Note Run the app on desktop client with developer preview on.
