Silverlight opening relative URI - works when debugging, fails when running outside VS

Question

My Silverlight project uses dane.xml file, which is located in ProjectName.Web/Client.Bin/dane.xml

private void ReadXML()
{
    WebClient client1 = new WebClient();
    client1.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client1_DownloadStringCompleted);
    link  = new Uri("dane.xml", UriKind.Relative);
    client1.DownloadStringAsync(filePath);
}

void client1_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
    if (e.Error != null)
    {
        MessageBox.Show(e.Error.ToString() + "\n\nURI=" + link.ToString());
        return;
    }
    // (...)
}

Everything is working fine when I run it from Visual Studio (Debug or Start without debugging). But now I'd like to start it outside VS, so I ran ProjectName.Web/ProjectNameTestPage.html - and loading dane.xml file failed, with following error from MessageBox:

Error when loading file dane.xml

System.Net.WebException: An exception occurred during a WebClient request.
---> System.NotSupportedException: The URI prefix is not recognized.
in System.Net.WebRequest.Create(Uri requestUri)
in System.Net.WebClient.GetWebRequest(Uri address)
in System.Net.WebClient.DownloadStringAsync(Uri address, Object userToken)
(...)

URI=dane.xml

What should I do to fix that?

I've already tried setting dane.xml in Solution Explorer as Resource and creating new Uri("ProjectName;component/dane.xml", UriKind.Relative);, but it fails when running on Visual Studio.

Problem solved. I've put my site on apache server (copy ProjectName.web folder and run ProjectNameTestPage.html) and now it works.
