Loading

Setup

1. Register a new application in the Azure Active Directory – 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 -host-header=rewrite 3978

3. 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

4. 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.io then your domain-name will be 1234.ngrok.io.
  • 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.
