Stage View: Manifest

Prerequisites

• .NET Core SDK version 6.0

  determine dotnet version

  dotnet --version

• Register a AAD aap registration in Azure portal.

• Also, register a bot with Azure Bot Service, following the instructions here.

• Ensure that you've enabled the Teams Channel

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

  NOTE: When you create your app registration, you will create an App ID and App password - make sure you keep these for later.

3. Setup NGROK

• Run ngrok - point to port 3978

  ngrok http -host-header=rewrite 3978

4. Setup for code

• Clone the repository

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

• Modify the /appsettings.json and fill in the following details:

  • {{Bot Id}} - Generated from Step 1 while doing AAd app registration in Azure portal.
  • {{ Bot Password}} - Generated from Step 1, also referred to as Client secret
  • {{ Application Base URL }} - Your application's base url. E.g. https://12345.ngrok.io if you are using ngrok.

• In a terminal, navigate to TabInStageView

  # change into project folder
  cd # TabInStageView

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

  A) From a terminal

  # run the bot
  dotnet run

  B) Or from Visual Studio

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

5. Setup Manifest for Teams

• This step is specific to Teams.

  • Edit the manifest.json contained in the ./Manifest 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 or Bot-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. Note: If you want to test your app across multi hub like: Outlook/Office.com, please update the manifest.json in the TabInStageView\Manifest_Hub folder with the required values.
  • Zip up the contents of the Manifest folder to create a Manifest.zip or Manifest_Hub folder to create a Manifest_Hub.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 ./Manifest folder, select the zip folder, and choose Open.
