Channel and group tabs in ASP.NET Core with MVC

In this quickstart we'll walk-through creating a custom channel/group tab with ASP.Net Core and MVC. We'll also use App Studio for Microsoft Teams to finalize your app manifest and deploy your tab to Teams.

Prerequisites

• .NET Core SDK version 6.0

  determine dotnet version

  dotnet --version

• Ngrok (For local environment testing) Latest (any other tunneling software can also be used)

• Teams Microsoft Teams is installed and you have an account

Included Features

• Tabs

Interaction with app

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 package (.zip file link below) to your teams and/or as a personal app. (Sideloading must be enabled for your tenant, see steps here).

Channel and group tabs in ASP.NET Core with MVC: Manifest

Setup

1. Run ngrok - point to port 3978 ngrok http 3978 --host-header="localhost:3978"

2. Clone the repository

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

3. If you are using Visual Studio

• Launch Visual Studio
• File -> Open -> Project/Solution
• Navigate to samples\tab-channel-group\mvc-csharp folder
• Select ChannelGroupTabMVC.sln file and open the solution

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

   • <<Guid>> with any random GUID.
   • <<Base-url>> 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.
   • validDomains 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.

5. 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 ./AppManifest folder, select the zip folder, and choose Open.
