Auth Provider Instance

 For this console application, I have used Client credentials provider. The client credential flow enables service applications to run without user interaction. Access is based on the identity of the application.  Click here to choose a Microsoft Graph authentication provider based on scenario. 

List Groups Graph API – Get all the groups using Graph API

List Groups

Permissions required

  • Permission Type – Application
  • Permissions – Group.Read.All, Directory.Read.All, Group.ReadWrite.All, Directory.ReadWrite.All

In this article, you will see how to perform the following tasks,

  • Register an Application in Azure – Register an app in Azure AD and add the required permissions to access the Graph API
  • Create and run the console application

Register an application in Azure

 Register an application in Azure AD to access the Graph API.

  1. Navigate to Azure portal.
  2. Search for App Registrations. Click App Registrations as show below

3. Click on the “New Registration”.

14. Copy the secret value which will be used in console application for authentication.

Create and run the Console Application

  1. Open Visual Studio 2019 and create a Console Application (.Net Framework).
  2. Install the following NuGet Packages either using Package Manager UI in Visual Studio or the Package Manager Console.
Install-Package Microsoft.Graph  
Install-Package Microsoft.Graph.Auth -IncludePrerelease

3. Open Program.cs and add the following code:

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 GraphAPIConsole  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            try  
            {  
                getUsersAsync().GetAwaiter().GetResult();  
            }  
            catch (Exception ex)  
            {  
                Console.WriteLine(ex.Message);  
            }  
            Console.ReadLine();  
        }  
  
        public async static Task getUsersAsync()  
        {  
            var clientId = "91110348-f503-477f-acad-73fdcf2ec370";  
            var tenantId = "1cb1e777-67af-48e4-88cb-e3865bb7085b";  
            var clientSecret = "b7qqTV0.0PceiCC0~5.Nr39joWbe.nOV.d";  
            IConfidentialClientApplication confidentialClientApplication = ConfidentialClientApplicationBuilder  
                .Create(clientId)  
                .WithTenantId(tenantId)  
                .WithClientSecret(clientSecret)  
                .Build();  
  
            ClientCredentialProvider authProvider = new ClientCredentialProvider(confidentialClientApplication);  
            GraphServiceClient graphClient = new GraphServiceClient(authProvider);  
  
            var groups = await graphClient.Groups.Request().Select(x => new { x.Id, x.DisplayName }).GetAsync();  
            foreach (var group in groups)  
            {  
                Console.WriteLine($"{group.DisplayName}, {group.Id}");  
            }  
        }  
    }  
}  

4. Press F5 and check the console.

That’s it!
