Change user agent in WP8.1 WebView

Question

This is for Windows Phone. I'm using windowsphone8.1 update 1. you know that the web interface works like that of android and iOS. How do I get the same interface in my wp8.1 web-apps? I downloaded and installed WP8.1 Update 1 SDK. I don't see Wp8.1 update 1 version to select when I open a new project. Can I get updated web interface in WP8.1 or Cyan updated users?

HttpRequestMessage httpRequestMessage = 
new HttpRequestMessage(HttpMethod.Post, new Uri("website"));
httpRequestMessage.Headers.Append("User-Agent", 
                "Custom User-Agent"); 

webView.NavigateWithHttpRequestMessage(
httpRequestMessage);

Obviously it works for one Uri

Windows Phone 8.1 Update 1 does not introduce any new public APIs for developers.

If you're working with the WebView (aka the WebBrowser) control in a Windows Phone 8.1 XAML project and you want to specify a different user-agent for the entire session, use...

[DllImport("urlmon.dll", CharSet = CharSet.Ansi)]
private static extern int UrlMkSetSessionOption(int dwOption, string pBuffer, int dwBufferLength, int dwReserved);

const int URLMON_OPTION_USERAGENT = 0x10000001;

public void ChangeUserAgent(string Agent)
{
    UrlMkSetSessionOption(URLMON_OPTION_USERAGENT, Agent, Agent.Length, 0);
}

void MainPage_Loaded(object sender, RoutedEventArgs e)
{
    ChangeUserAgent("My Custom User-Agent");
    wb.Navigate(new Uri("http://basquang.wordpress.com/2014/04/26/wp8-1-changing-windows-phone-8-1-webview-default-user-agent-in-all-outbound-http-requests/", UriKind.Absolute));
}
