Hi @Nerin Peter Chetty (For Azure)

I can't reproduce your problem, please refer to my code, it can perfectly lists all users in the Azure AD B2C tenant.

Frameworks:

Dependent packages:

using Azure.Identity;   
using Microsoft.Graph;  
using Newtonsoft.Json;  
  
var scopes = new[] { "https://graph.microsoft.com/.default" };  
  
var tenantId = "the tenant ID of the B2C tenant";  
  
// Values from app registration  
var clientId = "client id";  
var clientSecret = "client secret";  
  
// using Azure.Identity;  
var options = new TokenCredentialOptions  
{  
    AuthorityHost = AzureAuthorityHosts.AzurePublicCloud  
};  
  
// https://learn.microsoft.com/dotnet/api/azure.identity.clientsecretcredential  
var clientSecretCredential = new ClientSecretCredential(  
    tenantId, clientId, clientSecret, options);  
  
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);  
  
var users = await graphClient.Users  
      .Request()  
      .GetAsync();  
  
Console.WriteLine("users:" + JsonConvert.SerializeObject(users));
