I have been struggling with a CS1061 error for ‘.Request()’ and cannot seem to figure it out, if anyone can think of a solution or a work around it would be greatly appreciated!

The program is running .NET 8 and using Microsoft.graph, microsoft.graph.core and Azure.Identity packages, all up to date.

 static void UpdateUser()
 {
     var scopes = new[] { "https://graph.microsoft.com/.default" };

     var tenantId = "...";


     var clientId = "...";
     var clientSecret = "...";

     ClientSecretCredential clientSecretCredential = new ClientSecretCredential(tenantId, clientId, clientSecret);
     var graphClient = new GraphServiceClient(clientSecretCredential, scopes);

     Console.WriteLine("Updating a user...");

     Console.Write("Enter the Object ID of the user to update: ");
     string objectId = Console.ReadLine();

     try
     {

         var user = graphClient.Users[objectId].GetAsync().Result;

         // Display current user attributes
         Console.WriteLine($"Current attributes of the user with Object ID {objectId}:");
         Console.WriteLine($"Display Name: {user.DisplayName}");
         Console.WriteLine($"Given Name: {user.GivenName}");
         Console.WriteLine($"Surname: {user.Surname}");
         Console.WriteLine($"Email Address: {user.Identities[0].IssuerAssignedId}"); 
         Console.WriteLine($"Business Phone Number: {user.BusinessPhones?[0]}"); 

         // Prompt the user to update attributes
         Console.WriteLine("Enter new values for the user's attributes (press Enter to keep current value):");

         Console.Write("New Display Name: ");
         string newDisplayName = Console.ReadLine();

         Console.Write("New Given Name: ");
         string newGivenName = Console.ReadLine();

         Console.Write("New Surname: ");
         string newSurname = Console.ReadLine();

         Console.Write("New Email Address: ");
         string newEmailAddress = Console.ReadLine();

         Console.Write("New Business Phone Number: ");
         string newBusinessPhone = Console.ReadLine();

         // Update user attributes
         if (!string.IsNullOrEmpty(newDisplayName))
             user.DisplayName = newDisplayName;

         if (!string.IsNullOrEmpty(newGivenName))
             user.GivenName = newGivenName;

         if (!string.IsNullOrEmpty(newSurname))
             user.Surname = newSurname;

         if (!string.IsNullOrEmpty(newEmailAddress))
             user.Identities[0].IssuerAssignedId = newEmailAddress;

         if (!string.IsNullOrEmpty(newBusinessPhone))
         {
             if (user.BusinessPhones == null)
                 user.BusinessPhones = new List<string>();

             user.BusinessPhones.Clear(); 
             user.BusinessPhones.Add(newBusinessPhone); 
         }

         // Update the user in Azure AD B2C
         graphClient.Users[objectId].Request().UpdateAsync(user).Wait();
         Console.WriteLine("User updated successfully");
     }
     catch (Exception ex)
     {
         Console.WriteLine($"Error updating user: {ex.Message}");
     }
 }

Hopefully this information is suffice, if there is any other info I can provide that may help feel free to ask (I am fairly new to coding so good chance I have missed something!).

Thanks in advance.

I have tried rebuild and cleaning the program, I also asked chatGPT if it has any ideas why this may not work, but it could not provide a fix. All packages have been updated.
