Microsoft Graph Console Application

This post is providing the code for the build session “Integrating Microsoft Graph into your existing apps”,https://mybuild.techcommunity.microsoft.com/sessions/77302?source=sessions#top-anchor. Somehow I realized in that session they did not teach you how to get the Application Id,

Register the application as follow:

## Register a native application with the Application Registration Portal

1. Open a browser and navigate to the [Application Registration Portal](https://apps.dev.microsoft.com) and login using a **personal account** (aka: Microsoft Account) or **Work or School Account**.

2. Select **Add an app** at the top of the page.

> **Note:** If you see more than one **Add an app** button on the page, select the one that corresponds to the **Converged apps** list.

3. On the **Register your application** page, set the **Application Name** to **UWP Graph Tutorial** and select **Create**.

4. On the **UWP Graph Tutorial Registration** page, under the **Properties** section, copy the **Application Id** as you will need it later.

using Microsoft.Graph;

using Microsoft.Graph.Auth;

using Microsoft.Identity.Client;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace ConAppGraph

{

class Program

{

  static void Main(string[] args)

  {

    Run().GetAwaiter().GetResult();

    Console.Read();

}

  public static async Task Run()

  {

    var clientId = “Application ID”;

    var scopes = new List<string>() { “User.ReadBasic.All” }.ToArray();

    IPublicClientApplication clientApplication = InteractiveAuthenticationProvider.CreateClientApplication(clientId);

    InteractiveAuthenticationProvider authProvider = new InteractiveAuthenticationProvider(clientApplication, scopes);

    GraphServiceClient graphClient = new GraphServiceClient(authProvider);


    var users = await graphClient.Users

    .Request()

.    Select(e => new {

        e.DisplayName,

        e.GivenName,

        e.PostalCode

    } )

.    GetAsync();

    foreach (var user in users)

    {

        Console.WriteLine(user.GivenName);

    }

  }

}

}
