Google Drive .NET Quickstart Error for Credentials

I'm starting to study Google Drive's Api for a personal project in .NET, and I followed the step-by-step guide available on the google website

link

But when I was running the code at the time of obtaining the credentials happened this error:

        static void Main(string[] args)
        {
            UserCredential credential;

            using (var stream =
                new FileStream("client_secret.json", FileMode.Open, FileAccess.Read))
            {

            // Create Drive API service.
            var service = new DriveService(new BaseClientService.Initializer()

                HttpClientInitializer = credential,
                ApplicationName = ApplicationName,
            });

            // Define parameters of request.
            FilesResource.ListRequest listRequest = service.Files.List();
            listRequest.PageSize = 10;
            listRequest.Fields = "nextPageToken, files(id, name)";

            // List files.
            IList<Google.Apis.Drive.v3.Data.File> files = listRequest.Execute()
                .Files;
            Console.WriteLine("Files:");
            if (files != null && files.Count > 0)
            {
                foreach (var file in files)
                {
                    Console.WriteLine("{0} ({1})", file.Name, file.Id);
                }
            }
            else
            {
                Console.WriteLine("No files found.");
            }
            Console.Read();

        }
    }
}

Packages installed in the project as it is in the tutorial, plus settings in the client_secret.json file to always copy to the output as it is also in the tutorial:

Has this problem ever happened to anyone or anything like it?
