Bot Framework v4 Conversation Bot sample for Teams.

This bot has been created using Bot Framework. This sample shows how to incorporate basic conversational flow into a Teams application. It also illustrates a few of the Teams specific calls you can make from your bot.

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

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/57.teams-conversation-bot folder
   • Select TeamsConversationBot.csproj file

3. Run ngrok - point to port 3978

   ngrok http -host-header=rewrite 3978

4. Create Bot Framework registration resource in Azure

   • For bot handle, make up a name.
   • Select "Use existing app registration" (Create the app registration in Azure Active Directory beforehand.)
   • If you don't have an Azure account create an Azure free account here

5. In the new Azure Bot resource in the Portal,

   • Enable the Teams Channel
   • In Settings/Configuration/Messaging endpoint, enter the current https URL you were given by running ngrok. Append with the path /api/messages

6. 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.)

7. 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 Teams Apps/Manage your apps click "Upload a custom app". Browse to and Open the .zip file. At the next dialog, click the Add button.)

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

You can interact with this bot in Teams by sending it a message, or selecting a command from the command list. The bot will respond to the following strings.

1. Show Welcome

• Result: The bot will send the welcome card for you to interact with
• Valid Scopes: personal, group chat, team chat

2. MentionMe

• Result: The bot will respond to the message and mention the user
• Valid Scopes: personal, group chat, team chat

3. MessageAllMembers

• Result: The bot will send a 1-on-1 message to each member in the current conversation (aka on the conversation's roster).
• Valid Scopes: personal, group chat, team chat

You can select an option from the command list by typing @TeamsConversationBot into the compose message area and What can I do? text above the compose area.
