Teams Messaging Extensions Action Preview

Bot Framework v4 Teams Messaging Extension Action Preview sample.

This Messaging Extension has been created using Bot Framework.

  • It shows how to create a simple card based on parameters entered by the user from a Task Module.
  • It also displays the scenario where a Bot sends messages on behalf of a User. Attributing the message to that user can help with engagement and showcase a more natural interaction flow.

Prerequisites

  • Microsoft Teams is installed and you have an account
  • .NET Core SDK version 3.1
  • ngrok or equivalent tunnelling solution

To try this sample

Note these instructions are for running the sample on your local machine, the tunnelling solution is required because the Teams service needs to call into the bot.

  1. Clone the repository

    git clone https://github.com/Microsoft/botbuilder-samples.git

  2. If you are using Visual Studio

    • Launch Visual Studio
    • File -> Open -> Project/Solution
    • Navigate to samples/csharp_dotnetcore/53.teams-messaging-extensions-action-preview folder
    • Select TeamsMessagingExtensionsActionPreview.csproj file

  3. Run ngrok - point to port 3978

    ngrok http -host-header=rewrite 3978

  4. Create Bot Framework registration resource in Azure

  5. Update the appsettings.json configuration for the bot to use the Microsoft App Id and App Password from the Bot Framework registration. (Note the App Password is referred to as the "client secret" in the azure portal and you can always create a new client secret anytime.)

  6. This step is specific to Teams.

    • Edit the manifest.json contained in the teamsAppManifest 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)
    • Zip up the contents of the teamsAppManifest folder to create a manifest.zip
    • Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")

  7. Run your bot, either from Visual Studio with F5 or using dotnet run in the appropriate folder.

Interacting with the bot in Teams

Note the manifest.json specifies that this bot will be available in "personal", "team" and "groupchat" scopes and the command will be available in the "commandBox", "compose" and "message" context.

Click the Messaging Extension icon in the Compose Box's Messaging Extension menu.

Deploy the bot to Azure
