Google Site Verification API .NET redirect uri is not adopted

(http deleted because of reputation) I'm testing the Google Site Verification API with the "GoogleApisSamples" Projects from Google, but I have a problem concerning the redirect uri.. I get the client_secrets.json (with redirect uris set) from my GoogleDrive Application, but the redirect uri that this programm gets is something like "localhost:1168/authorize/" (it changes). I set the redirect uri to "www.google.com" and "www.google.com/".

namespace SiteVerification.VerifySite

{

internal class Program
{
    [STAThread]
    static void Main(string[] args)
    {
        // Display the header and initialize the sample.
        Console.WriteLine("Site Verification sample");
        Console.WriteLine("========================");

        UserCredential credential;
        using (var stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read))
        {
            credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                new[] { SiteVerificationService.Scope.Siteverification },
                "user", CancellationToken.None, new FileDataStore("SiteVerification.VerifySite")).Result;
        }

        // Create the service.
        var service = new SiteVerificationService(new BaseClientService.Initializer
            {
                HttpClientInitializer = credential,
                ApplicationName = "SiteVerification API Sample",
            });
        RunVerification(service);

        Console.WriteLine("Press any key to continue...");
        Console.ReadKey();
    }

    /// <summary>
    /// This method contains the actual sample code.
    /// </summary>
    private static void RunVerification(SiteVerificationService service)
    {
        // Request user input.
        Console.WriteLine("Please enter the URL of the site to verify:");
        var site = Console.ReadLine();
        Console.WriteLine();

        // Example of a GetToken call.
        Console.WriteLine("Retrieving a meta token ...");
        var request = service.WebResource.GetToken(new SiteVerificationWebResourceGettokenRequest()
        {
            VerificationMethod = "meta",
            Site = new SiteVerificationWebResourceGettokenRequest.SiteData()
            {
                Identifier = site,
                Type = "site"
            }
        });
        var response = request.Execute();
        Console.WriteLine("Token: " + response.Token);
        Console.WriteLine();

        Console.WriteLine("Please place this token on your webpage now.");
        Console.WriteLine("Press ENTER to continue");
        Console.ReadLine();
        Console.WriteLine();

        // Example of an Insert call.
        Console.WriteLine("Verifying...");
        var body = new SiteVerificationWebResourceResource();
        body.Site = new SiteVerificationWebResourceResource.SiteData();
        body.Site.Identifier = site;
        body.Site.Type = "site";
        var verificationResponse = service.WebResource.Insert(body, "meta").Execute();

        Console.WriteLine("Verification:" + verificationResponse.Id);
        Console.WriteLine("Verification successful!");
    }
}

}

And my "client_secrets.json" (I changed the Stuff in caps)

{
"web": {
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "client_secret": "CLIENT_SECRET",
    "token_uri": "https://accounts.google.com/o/oauth2/token",
    "client_email": "STUFF",
    "redirect_uris": [
        "http://www.google.com/",
        "http://www.google.com"
    ],
    "client_x509_cert_url": "STUFF",
    "client_id": "CLIENT_ID",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "javascript_origins": [
        "https://www.google.com"
    ]
}

}

And the error I get is:

400. That’s an error.

Error: redirect_uri_mismatch

Application: GoogleApisSamples

The redirect URI in the request: localhost:1168/authorize/ did not match a registered redirect URI.

Redirect URI must match the location you want the Authentication to be returned to

For a Client ID for native application you could set it to the following:

 Redirect URIs     urn:ietf:wg:oauth:2.0:oob  
                   http://localhost

For Client ID for web application it would be something more like this

    Redirect URIs     
         http://localhost/google-api-php-client-samples/oauth2.php 

Web must patch to a actual file.

This example might be easer to use the loading the file into a stream.

string[] scopes = new string[] { SiteVerificationService.Scope.Siteverification };
// here is where we Request the user to give us access, or use the Refresh Token that was previously stored in %AppData%
UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets
                                           {
                                            ClientId = CLIENT_ID,
                                            ClientSecret = CLIENT_SECRET
                                             },
                   scopes,
                   Environment.UserName,
                   CancellationToken.None,
                   new FileDataStore"Daimto.SiteVerification.Auth.Store")).Result;

// Create the service.
var service = new SiteVerificationService(new BaseClientService.Initializer
            {
                HttpClientInitializer = credential,
                ApplicationName = "SiteVerification API Sample",
            });
