Version detection with Silverlight

Question

How can I efficiently and effectively detect the version and, for that matter, any available information about the instance of Silverlight currently running on the browser?<

I got this from http://forums.asp.net/p/1135746/1997617.aspx#1997617 which is the same link Stu gave you. I just included the code snippet.

Silverlight.isInstalled = function(d)
{
    var c = false, a = null;
    try
    {
        var b = null;
        if(Silverlight.ua.Browser == "MSIE")
            b = new ActiveXObject("AgControl.AgControl");
        else
            if(navigator.plugins["Silverlight Plug-In"])
            {
                a = document.createElement("div");
                document.body.appendChild(a);
                a.innerHTML = '';
                b = a.childNodes[0]
            }

        if(b.IsVersionSupported(d))
            c = true;
        b = null;
        Silverlight.available = true
    }
    catch(e)
    {
        c=false
    }

    if(a)
        document.body.removeChild(a);
    return c
};
