Interaction with app

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

Realtime meeting and participant events: Manifest

Prerequisites

• .NET Core SDK version 6.0

  # determine dotnet version
  dotnet --version

• Publicly addressable https url or tunnel such as dev tunnel or ngrok latest version or Tunnel Relay

Setup

NOTE: The free ngrok plan will generate a new URL every time you run it, which requires you to update your Azure AD registration, the Teams app manifest, and the project configuration. A paid account with a permanent ngrok URL is recommended.

1. Setup for Bot

   • Register Azure AD application resource in Azure portal

   • In Azure portal, create a Azure Bot resource.

   • Ensure that you've enabled the Teams Channel

   • While registering the bot, use https://<your_tunnel_domain>/api/messages as the messaging endpoint.

NOTE: When you create your bot 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

3. Setup for code

• Clone the repository

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

• Navigate to samples/meetings-events/csharp

  • Modify the /appsettings.json and fill in the {{ MicrosoftAppId }},{{ MicrosoftAppPassword }} with the values received while doing Microsoft Entra ID app registration in step 1.

• Run the app from a terminal or from Visual Studio, choose option A or B.

  A) From a terminal

  # run the app
  dotnet run

  B) Or from Visual Studio

  • Launch Visual Studio
  • File -> Open -> Project/Solution
  • Navigate to MeetingEvents folder
  • Select MeetingEvents.csproj file
  • Press F5 to run the project

4. Setup Manifest for Teams

Modify the manifest.json in the /AppManifest folder and replace the following details

• <<App-ID>> with your Microsoft Entra ID app registration id
• <<VALID 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.
• Zip the contents of AppManifest folder into a manifest.zip, and use the manifest.zip to deploy in app store
• • Upload the manifest.zip to Teams
    • Select Apps from the left panel.
    • Then select Upload a custom app from the lower right corner.
    • Then select the manifest.zip file from AppManifest.
    • Install the App in Teams Meeting

Note: If you are facing any issue in your app, please uncomment this line and put your debugger for local debug.
