My code:

X509Certificate2 certificate = new X509Certificate2(@"test.p12", "notasecret", X509KeyStorageFlags.Exportable);

    ServiceAccountCredential credential = new ServiceAccountCredential(
        new ServiceAccountCredential.Initializer("test@developer.gserviceaccount.com")
        {
            Scopes = new[] { YouTubeService.Scope.YoutubeUpload, YouTubeService.Scope.Youtube, YouTubeService.Scope.YoutubeReadonly }
        }.FromCertificate(certificate));

    if (credential.RequestAccessTokenAsync(CancellationToken.None).Result)
    {
        String AuthenticationKey = credential.Token.AccessToken;
    }

        var youtubeService = new YouTubeService(new BaseClientService.Initializer()
          {
              ApplicationName = "test",

              HttpClientInitializer = credential
          });

          var video = new Video();
          video.Snippet = new VideoSnippet();
          video.Snippet.Title = "Test Video";
          video.Snippet.Description = "Test Vide Description";
          video.Snippet.Tags = new string[] { "test" };
          video.Snippet.CategoryId = "22";


          video.Status = new VideoStatus();
          video.Status.PrivacyStatus = "private"; 
          var filePath = @"test.mp4"; 

          using (var fileStream = new FileStream(filePath, FileMode.Open))
          {

            var videosInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "video/*");
            var uploadResult = videosInsertRequest.Upload();
            uploadResult = uploadResult;
          }

Can Anyone help?
