Launch WPF from ASP.NET page button click

I am trying to write an aspx page containing a button whose click event should result in opening of a WPF form for further processing. I am trying to use a new process object to launch the WPF application.

I am using the following code in the code behind:

protected void Btn_Click(object sender, EventArgs e)
        {
            Process WPF = new Process();
            WPF.StartInfo.FileName = "WpfApplication1.exe";
            WPF.Start();
        }

On execution, the button click executes without any exception, but the WPF window is not opened.

Can someone please help me.

Thanks.

I googled a bit and found the following discussion: social.msdn.microsoft.com/forums/en-US/wpf/thread/… The summary is WPF cannot be launched from ASP.NET. For that XBAP is required. – Jake
your comment is the answer (it's exactly what i would have said in my answer). – slugster
Please do not post that as a comment, post it as an answer and accept it. – H.B.

The code you posted starts (or attempts to start) the WPF application on the server

If you want the client to run a WPF application you could use an XBAP application or a regular WPF application that is distributed through ClickOnce deployment so you can add a link to the application on your web page.

To launch WPF form from asp.net go to the View Code of code behind and Create an object for the WPF form and in the Page_Load event paste the following code

 protected void Page_Load(object sender, EventArgs e)
        {
            Thread t = new Thread(() =>
            {
                mainWindow = new MainWindow();
                mainWindow.Show();
                System.Windows.Threading.Dispatcher.Run();
            });
            t.SetApartmentState(ApartmentState.STA);
            t.IsBackground = true;
            t.Start();
            createDB();
        }
