User Control RegisterScriptDescriptors Circular Reference

Question

Im not sure why I am running into a circular reference when trying to register script descriptors. Here is my code for the user control:

    protected void Page_Load(object sender, EventArgs eventArguments)
    {
    }

    protected override void OnPreRender(EventArgs eventArguments)
    {
        ScriptManager.GetCurrent(Page).RegisterScriptControl(this);
        base.OnPreRender(eventArguments);
    }

    protected override void Render(HtmlTextWriter htmlWriter)
    {
        ScriptManager.GetCurrent(Page).RegisterScriptDescriptors(this);
        base.Render(htmlWriter);
    }

I am getting the exception ( System.InvalidOperationException: A circular reference was detected while serializing an object of type 'ASP.global_asax'.) on RegisterScriptDescriptors.

Here is my entire Global.asax

<%@ Application Language="C#" %>
<%@ Import Namespace="System.Web.Optimization" %>
<%@ Import Namespace="System.Web.Routing" %>

<script runat="server">

void Application_Start(object sender, EventArgs e)
{
    StockPicker.BundleConfig.RegisterBundles(BundleTable.Bundles);
}

</script>

Sorry, but I answered it after struggling a bit. I was using another user control in the control and I was using that control in the GetScriptDescriptors method. This was causing the circular reference.
