Sequential workflow adaptive cards C#

This sample illustrates sequential workflow, user specific views and upto date adaptive cards bot and the list of incident created can be seen in messaging extension and can share a specific incident to the chat/team.

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 manifest (.zip file link below) to your teams and/or as a personal app. (Sideloading must be enabled for your tenant, see steps here).

Sequential workflow adaptive cards: Manifest

Prerequisites

• Microsoft Teams is installed and you have an account
• .NET Core SDK version 6.0
• dev tunnel or ngrok latest version or equivalent tunnelling solution

Setup

1. Register a new application in the Microsoft Entra ID – App Registrations portal.

2. Setup for Bot

   • Register a Microsoft Entra ID 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_tunnel_domain>/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 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

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:

  • {{YOUR-MICROSOFT-APP-ID}} - Generated from Step 1 is the application app id
  • {{YOUR-MICROSOFT-APP-SECRET}} - Generated from Step 1, also referred to as Client secret

• If you are using Visual Studio

• Launch Visual Studio

• File -> Open -> Project/Solution

• Navigate to samples/bot-sequential-flow-adaptive-cards/csharp/ folder

• Select SequentialUserSpecificFlow.csproj file

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

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}} (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-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.
  • Zip up the contents of the Manifest 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 ./AppManifest folder, select the zip folder, and choose Open.
  • Select Add in the pop-up dialog box. Your app is uploaded to Teams.

Note: If you are facing any issue in your app, please uncomment this line and put your debugger for local debug.

Running the sample

1. In Teams, Once the app is successfully installed in a group chat, ping the bot by @mentioning it. Bot will reply with a card showing that the person has initiated the incident.

2. Using refresh activity only the person who has initiated will be able to proceed further by entering the details of the incident and assign it to a person from the group chat, while others in the group chat will still be able to see only the initiated card.

3. User who has initiated the incident will be able to enter the details using the series of cards in a sequential flow and submit it for the further approval/rejection process.

4. Once the details are submitted and assigned to a person from the group chat, it will send an updated card to the chat with all the entered details.

5. Now, only the person assigned to will be able to either approve or reject it.

6. After the approval/rejection of the card, the final updated card will be sent to the group chat.

Running the sample( Interaction with message extension)

1. On selecting app from messaging extension,it checks whether bot is installed in chat/team. If not installed, user will get a option for justInTimeInstallation card.

   

2. After successful installation, list of all incident will be available in messaging extension.

   .

3. User can select any incident from the list and can share to that chat/team.
