Displaying a local PDF file in WPF with WebBrowser-Control

I'm trying to display a local PDF file in a WebBrowser-Control. I didn't want to use the Adobe-Libraries, because they don't support 64-bit. Now I already have the code to display a PDF, but only if it is not on the local HDD. When I right-clicked on the WebBrowser-Control and displayed the SourceCode of the HTML, I saved it as an HTML-File to check, if the HTML-Code is correctly working. Well, it works.

My window only consists of a maximized WebControl. I think the problem are the Security Settings of the local Internet Explorer. I read that a custom IInternetSecurityManager could solve the problem, but I don't know how to implement it... :/

I'm using C# with .NET Framework 4.0

Here is my code:

    void MainWindow_Loaded(object sender, RoutedEventArgs e)
    {            
        string url = "C:/test.pdf";
        string html = "<!-- saved from url=(0014)about:internet -->\n<html>\n<body>\n<embed src=\"" + url + "\" width=\"100%\" height=\"100%\"/>\n</body>\n</html>";
        webBrowser.NavigateToString(html); // System.Windows.Controls.WebBrowser
    }

I the "saved from URL" part does only work if I directly open the HTML-Code in IE, so please tell me what to do, to get this code work... Maybe you have a better solution for my problem. Thanks for your help!

Regards, Chris

Just use 

webBrowser.Navigate("file:///" + url);
