Personal Tab with ASP.NET Core

In this quickstart we'll walk-through creating a custom personal tab with C# and ASP.Net Core Razor pages. We'll also use App Studio for Microsoft Teams to finalize your app manifest and deploy your tab to Teams.

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).

Personal Tab: Manifest

Prerequisites

• .NET Core SDK version 6.0

  determine dotnet version

  dotnet --version

• dev tunnel or Ngrok (For local environment testing) latest version (any other tunneling software can also be used)

• Teams Microsoft Teams is installed and you have an account

Setup

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. If you are using Visual Studio

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

   • <> 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 and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.
   • 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 and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.

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
