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

Meeting-Tabs: Manifest

Prerequisites

• .NET Core SDK version 6.0

  determine dotnet version

  dotnet --version

• dev tunnel or ngrok latest version or equivalent tunnelling solution

• Teams Microsoft Teams is installed and you have an account

• 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.

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. Setup

   Register your application with Azure AD:

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

   • Select New Registration and on the register an application page, set following values: * Set name to your app name. * Choose the supported account types (any account type will work) * Leave Redirect URI empty. * Choose Register.

   • On the overview page, copy and save the Application (client) ID, Directory (tenant) ID. You’ll need those later when updating your Teams application manifest and in the appsettings.json.

   • Ensure that you've enabled the Teams Channel

3. Clone the repository

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

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

   A) From a terminal, navigate to samples/meeting-tabs/csharp

   # run the app
   dotnet run

   B) Or from Visual Studio

   • Launch Visual Studio
   • File -> Open -> Project/Solution
   • Navigate to samples/meeting-tabs/csharp folder
   • Select AppInMeeting.sln file
   • Press F5 to run the project

5. In a terminal, navigate to samples/meeting-tabs/csharp/ClientApp

   • Inside ClientApp folder execute the below command.

     # npm install

6. 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 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)

• Edit the manifest.json for <<DOMAIN-NAME>> 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 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 Teams Apps/Manage your apps click "Upload an app". Browse to and Open the .zip file. At the next dialog, click the Add button.)

• Add the app to team/groupChat scope (Supported scopes).
