<httpRuntime executionTimeout="6000" maxRequestLength="100000" />

but same issue occur. Please help me Code is as Follws:-

YouTubeRequest request = new YouTubeRequest(settings);
        //request.Settings.Maximum = 9999999;
        request.Settings.Timeout = 60 * 60 * 1000;          
        Video newVideo = new Video();

        newVideo.Title = TextBox1.Text;
        newVideo.Tags.Add(new MediaCategory("People", YouTubeNameTable.CategorySchema));
        newVideo.Keywords = "cars, funny";
        newVideo.Description = TextBox2.Text;
        newVideo.YouTubeEntry.Private = false;
        newVideo.YouTubeEntry.AccessControls.Add(new YtAccessControl("list", "denied"));
        newVideo.Tags.Add(new MediaCategory("mydevtag, anotherdevtag", YouTubeNameTable.DeveloperTagSchema));



        newVideo.YouTubeEntry.MediaSource = new MediaFileSource(f.ToString(), "video/x-flv");


        Video createdVideo = request.Upload(newVideo);

Just add these 3 lines in your code and try,

 YouTubeService service = new YouTubeService("Test", DEVELOPERKEY);
        ((GDataRequestFactory)request.Service.RequestFactory).Timeout = 9999999; 
        ((GDataRequestFactory)service.RequestFactory).KeepAlive = false;

Mark this as answer if your problem solved.
