How can I call the .Invoke method of a Delegate.Target?

Question

Given the following method :

public static void ExecuteAsync( this EventHandler eH, object sender, EventArgs eA ) {
    eH.GetInvocationList( ).Cast<EventHandler>( ).ToList( ).ForEach( e => {         
        e.BeginInvoke( sender, eA, IAR =>
            ( ( IAR as AsyncResult ).AsyncDelegate as EventHandler ).EndInvoke( IAR ), null );
    } );
}

I noticed that e has a property Target.

When I was looking further into it I discovered I can check if e.Target is System.Windows.Controls.Control or e.Target is System.Windows.Forms.Control.

This is awesome because in the case of using this extension, as a matter of convenience (and me being lazy), I want to be able to tell if the delegate target needs to invoke the delegate or not (In the case of WinForms : Control.Invoke( foo ); In the case of WPF : Control.Dispatcher.Invoke( foo )).

I don't need to know how to cast the object to what it's actual type is (I can live without that) : I just need to know if how I can cast the object such that I can access the InvokeRequired property and Invoke methods (in the case of a WinForms control), or the Dispatcher property (For access to the Dispatcher.CheckAccess( ) function and Dispatcher.Invoke( ) method).

Is this possible? How can I go about doing this? (I've tried casting e.Target to System.Windows.Control.Control but the result does not have a Dispatcher property).

EDIT

As per the request for the casting code (and imports/references) :

To determine if it is a WPF control :

( if e.Target is System.Windows.Controls.Control ){ //Fully Qualified
    ( e.Target as System.Windows.Controls.Control)./*...*/;
}

To determine if it is a WinForms control :

( if e.Target is System.Windows.Forms.Control ){ //Fully Qualified
    ( e.Target as System.Windows.Forms.Control )./*...*/;
}

The project makes reference to several libraries :

Microsoft.CSharp
MySql.Data
PresentationFramework
System
System.Configuration
System.Configuration.Install
System.Core
System.Data
System.Data.DataSetExtensions
System.Drawing
System.Management
System.Windows.Forms
System.Xml
System.Xml.Linq

Doesn't that work for you. It's not the most elegant way but does the job of checking whether the target is a WPF or WinForms control:

if (e.Target is System.Windows.Controls.Control)
{
    var wpfTarget = ((System.Windows.Controls.Control)e.Target);
    if (wpfTarget.Dispatcher.CheckAccess()) // check if on dispatcher thread
    {
        wpfTarget.Dispatcher.Invoke(/*...*/);
    }

}
else if (e.Target is System.Windows.Forms.Control)
{
    var formsTarget = (System.Windows.Forms.Control)e.Target;
    if (formsTarget.InvokeRequired)
    {
        formsTarget.Invoke(/*...*/);
    }
}

In VisualStudio I have Intelisense support for the Dispatcher on the wpfTarget:

Below the references I've included

using System;

using System.Linq;
using System.Runtime.Remoting.Messaging;
using System.Text;
using System.Threading.Tasks;

using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;

of which only four are in use:
