This sample demonstrates how to use the Microsoft Graph .NET SDK to access data in Office 365 from Microsoft Bot Framework bots.

NOTE: This sample was originally built from a tutorial published on the Microsoft Graph tutorials page. That tutorial has been removed.

To run the completed project in this folder, you need the following:

• The .NET Core SDK 6.x installed on your development machine.
• Bot Framework Emulator
• ngrok
• Either a personal Microsoft account with a mailbox on Outlook.com, or a Microsoft work or school account with an Exchange Online mailbox.
• An Azure subscription and an account with the Application developer, Application administrator, Cloud application administrator, or Global administrator role.

If you don't have a Microsoft account, there are a couple of options to get a free account:

• You can sign up for a new personal Microsoft account.
• You can sign up for the Microsoft 365 Developer Program to get a free Office 365 subscription.

If you don't have an Azure subscription, you can create an account for free.

1. Open a browser and navigate to the Azure Portal. Login using the account associated with your Azure subscription.

2. Select the upper-left menu, then select Create a resource.

3. On the New page, search for Azure Bot and select Azure Bot.

4. On the Azure Bot page, select Create.

5. Fill in the required fields. The Bot handle field must be unique. Be sure to review the different pricing tiers and select what makes sense for your scenario. If this is just a learning exercise, you may want to select the free option.

6. For Type of App, select Multi Tenant.

   NOTE: https://token.botframework.com/.auth/web/redirect is the default Bot Framework OAuth redirect URL for the public Azure cloud with no data residency requirements. Depending on your environment, you may need to use a different redirect URL. See OAuth URL support in Azure Bot Service for more information.

4. Select Register. On the Graph Calendar Bot Auth page, copy the value of the Application (client) ID and save it, you will need it in the following steps.

5. Select Certificates & secrets under Manage. Select the New client secret button. Enter a value in Description and select one of the options for Expires and select Add.

   {
     "MicrosoftAppId": "YOUR_BOT_APP_ID_HERE",
     "MicrosoftAppPassword": "YOUR_BOT_PASSWORD_HERE"
   }

2. Replace YOUR_BOT_APP_ID_HERE with the Application (client) ID of your bot. (Step 13 of Create an Azure Bot in Azure portal)

3. Replace YOUR_BOT_PASSWORD_HERE with the client secret of your bot. (Step 12 of Create an Azure Bot in Azure portal)

You can run this sample from your command-line interface (CLI), Visual Studio Code, or Visual Studio.

1. In your CLI, navigate to the GraphCalendarBot directory.

2. Run the bot with the following command.

   dotnet run
