Update user using C# client for Graph API

Question

So many questions about this on Stack Overflow. Some back in 2016 says that an application permission on Directory is necessary to update User profile, but that permission no longer exists.

I think it should be sufficient to have User.ReadWrite permission to be able to update profile information on the current user. Shouldn't this code just work with that permission set?

        [HttpPost]  
        [ValidateAntiForgeryToken]  
        public async Task<IActionResult> Index([Bind("Id,Name,FirstName,LastName,City,Email,HomePage,Biography,BirthDate")] ProfileViewModel viewModel)  
        {  
            if (ModelState.IsValid)  
            {  
                var user = await _graphServiceClient.Me.Request().GetAsync();  
                var updatedValues = new User  
                {  
                    City = viewModel.City  
                };  
                var updatedUser = await _graphServiceClient.Users[user.Id].Request().UpdateAsync(updatedValues);  
  
                return RedirectToAction(nameof(Index));  
            }  
  
            return View(viewModel);  
        }  

updatedUser is null, and I don't get any exception. Looks like a bug to me. I've wasted a day on this now, so I think I'll just create my own storage for user profile data and implement my own API.

Hi @ eivind1980 , Sure i can understand that this is a kind of limitation more than a bug with the permissions, but as per document for updating user details these are the permissions required.

Reference document:https://learn.microsoft.com/en-us/graph/api/user-update?view=graph-rest-1.0&tabs=csharp#permissions

But if you want you raise a Feature request for this in the Microsoft portal and upvote it: https://techcommunity.microsoft.com/t5/microsoft-365-developer-platform/idb-p/Microsoft365DeveloperPlatform
