Message reminder with messaging extension action

This sample shows a feature where user can schedule a task from messaging extension action and get a reminder card at a scheduled time.

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

** Message reminder with messaging extension action:** Manifest

Prerequisites

• .NET Core SDK version 6.0

  determine dotnet version

  dotnet --version

• Ngrok (For local environment testing) Latest (any other tunneling software can also be used)

• Teams Microsoft Teams is installed and you have an account

Setup

1. Register a new application in the Azure Active Directory – App Registrations portal.

2. Setup for Bot

• 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 3978 --host-header="localhost: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:

• {{Microsoft-App-Id}} - Generated from Step 1 is the application app id

• {{ Microsoft-App-Password}} - Generated from Step 1, also referred to as Client secret

• {{ Application Base Url }} - Your application's base url. E.g. https://12345.ngrok-free.app if you are using ngrok.

• From a terminal, navigate to samples/msgext-message-reminder/csharp

  # run the bot
  dotnet run

Launch Visual Studio

• File -> Open -> Project/Solution
• Navigate to folder where repository is cloned then samples/msgext-message-reminder/csharp/MessagingExtensionReminder.sln
• Press F5 to run the project

5. 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-free.app then your domain-name will be 1234.ngrok-free.app.
  • 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: If you are facing any issue in your app, please uncomment this line and put your debugger for local debug.
