  //Create
        [HttpPost]
        public async Task<IActionResult> Create(AddPollRequest addPollRequest)
        {
            var result = await HttpContext.AuthenticateAsync(
                 CookieAuthenticationDefaults.AuthenticationScheme
              );


            addPollRequest.UserId = await UserInformation.GetGoogleId(result); <-- this line

            var domainPoll = mapper.Map<Poll>(addPollRequest);
            await pollRepository.CreatePollAsync(domainPoll);
            return RedirectToAction("Index", "Home");

        }

  //Create

This is the userinformation class:

 public static class UserInformation
 {
     public static string GetGoogleId(AuthenticationResult result)
     {
         if (result.ClaimsPrincipal == null)
             throw new Exception("Could not authenticate");

         var claims = result
             .ClaimsPrincipal.Identities.FirstOrDefault()
             ?.Claims.Select(claim => new
             {
                 claim.Issuer,
                 claim.OriginalIssuer,
                 claim.Type,
                 claim.Value
             })
             .ToList();

         User newUser;
         string? userName = null;
         string? userEmail = null;

         if

             (claims == null || claims.Count == 0)
         {
             throw new ArgumentOutOfRangeException("Claims count cannot be 0");
         }

         var googleId = claims
             .FirstOrDefault(c =>
                 c.Type == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier"
             )
             .Value;
         return googleId;
     }
 }

 public static class UserInformation
 {
     public static string GetGoogleId(AuthenticationResult result)
     {
         if (result.ClaimsPrincipal == null)
             throw new Exception("Could not authenticate");

         var claims = result
             .ClaimsPrincipal.Identities.FirstOrDefault()
             ?.Claims.Select(claim => new
             {
                 claim.Issuer,
                 claim.OriginalIssuer,
                 claim.Type,
                 claim.Value
             })
             .ToList();

         User newUser;
         string? userName = null;
         string? userEmail = null;

         if

             (claims == null || claims.Count == 0)
         {
             throw new ArgumentOutOfRangeException("Claims count cannot be 0");
         }

         var googleId = claims
             .FirstOrDefault(c =>
                 c.Type == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier"
             )
             .Value;
         return googleId;
     }
 }

Because you're trying to use two completely different types?

Keswiik•8mo ago

One is AuthenticateResult from this extension method: https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.authentication.authenticationhttpcontextextensions.authenticateasync?view=aspnetcore-8.0

AuthenticationHttpContextExtensions.AuthenticateAsync Method (Micro...

Authenticate the current request using the default authentication scheme. The default authentication scheme can be configured using DefaultAuthenticateScheme.

Keswiik•8mo ago

While the method you've written is expecting AuthenticationResult from an entirely different namespace

AresOP•8mo ago

i know that but I did using icrosoft.AspNetCore.Authentication.AuthenticateResult at the top of the file and it only gives me the option for Microsoft.Identity.Client.AuthenticationResult

Keswiik•8mo ago

public static string GetGoogleId(AuthenticationResult result) fix the type name of your argument here and see if you're able to import the correct namespace

AresOP•8mo ago

let me show you something do you see what i mean? i only have one option

Keswiik•8mo ago

Please read the type names I posted earlier. You're not typing the correct one.

How do i solve this type error?
