  We had tried implementing the provided solution, but we are getting activator chain error when trying to call the controller.

  Additionally, is there any way for us to retrieve the token at the Pages or AppServices? Given that the ABP MVC solution is design for the request to be access through Pages instead of Controller.

  Getting access-token from azure-ad is related with Microsoft and completely out of our scope.

  However i will try to help you;

  I willl use client credential flow using ConfidentialClientApplicationBuilder of Microsoft.Identity.Client package.

  Create a Page something like: <br>

  public class AzurePage : PageModel
  {
      IConfidentialClientApplication app;
      private const string clientId = "my-client-id-in-appsettings";
      private const string tenantId = "my-tenant-id-in-appsettings";
      private const string clientSecret = "my-client-secret-in-appsettings";
  
      public string azureAccessToken = string.Empty;
  
      public AzurePage()
      {
          string authority = $"https://login.microsoftonline.com/{tenantId}/v2.0/";
  
          app = ConfidentialClientApplicationBuilder.Create(clientId)
              .WithClientSecret(clientSecret)
              .WithAuthority(new Uri(authority))
              .Build();
      }
  
      public async Task<IActionResult> OnGet()
      {
          string[] scopes = new string[] {  "https://graph.microsoft.com/.default" };
  
          AuthenticationResult result = null;
          try
          {
              result = await app.AcquireTokenForClient(scopes)
                  .ExecuteAsync();
              azureAccessToken = result.AccessToken;
          }
          catch(MsalServiceException ex)
          {
              // AADSTS70011
              // Invalid scope. The scope has to be of the form "https://resourceurl/.default"
              // Mitigation: this is a dev issue. Change the scope to be as expected
          }
  
          return Page();
      }
  

  Result:

  

  and Jwt.io:

  

  Use IConfidentialClientApplication wherever you need.
