Run apps in Windows Phone

Question

I'm trying to make application, in which are used icons of some social sites, like facebook.

So the application looks like:

If you click on Facebook:

public void Facebook_Click()
{
    **Here must be code to detect installed applications**
    if (detected=true)
    {
          RunApplication (facebook);
    }
    else
    {
          OpenBrowser on page Facebook.com
    }
}

How to detect installed apps and run them?

Before saying it is impossible:

Auto-launching apps using file and URI associations for Windows Phone 8:

Maybe someone tried this?

Answer 1

there is no way to know what App are installed on the user's phone. You can open a link in web browser, but cannot do that with apps that haven't got URI associations as Alaa Masoud said.
