Key features

Prerequisites

• Microsoft Teams is installed and you have an account (not a guest account)
• .NET 6.0 SDK.

      # determine dotnet version
      dotnet --version

• ngrok or equivalent tunneling solution
• M365 developer account or access to a Teams account with the appropriate permissions to install an app.

Run app locally

Register your application with Azure AD

1. Register a new application in the Azure Active Directory – App Registrations portal.
2. On the overview page, copy and save the Application (client) ID, Directory (tenant) ID. You’ll need those later when updating your Teams application manifest and in the appsettings.json.
3. Navigate to API Permissions, and make sure to add the follow permissions:

• Select Add a permission

•  Select Microsoft Graph -> Application permissions.

  • Calendars.ReadWrite
  • Calendars.Read

• Click on Add permissions. Please make sure to grant the admin consent for the required permissions.

4. Navigate to the Certificates & secrets. In the Client secrets section, click on "+ New client secret". Add a description (Name of the secret) for the secret and select “Never” for Expires. Click "Add". Once the client secret is created, copy its value, it need to be placed in the appsettings.json file.

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 app.

1. Clone the repository

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

2. Launch Visual Studio

• File -> Open -> Project/Solution
• Navigate to folder where repository is cloned then samples/EventMeeting/csharp/EventMeeting.sln

3. Start ngrok on localhost:3978

• Open ngrok and run command ngrok http -host-header=rewrite 3978
• Once started you should see link https://41ed-abcd-e125.ngrok.io. Copy it, this is your baseUrl that will used as endpoint for Azure bot.

4. Update appsettings.json

Update configuration with the MicrosoftAppId, MicrosoftAppPassword and MicrosoftAppTenantId.

5. Modify the manifest.json in the /AppPackage folder

Replace the following details:

• {{APP-ID}} with any guid id value.
• {{BASE-URL}} with base Url domain. E.g. if you are using ngrok it would be https://1234.ngrok.io then your domain-name will be 1234.ngrok.io.
• Zip up the contents of the Manifest folder to create a manifest.zip
• Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")
