How to render XNA GraphicsDevice to Windows Forms Graphics object?

I use XNA in Windows Forms. According to Microsoft tutorial, the control that uses XNA should have something like this in OnPaint():

GraphicsDevice.Present(srcRectangle, null, this.Handle);

But I wanted to draw additional things with Windows Forms Graphics object. I can do it just fine placing drawing code after GraphicsDevice.Present(), but I get horrible flickering. That's why I thought of setting double buffering this way:

        protected override CreateParams CreateParams
        {
            get
            {
                var cp = base.CreateParams;
                cp.ExStyle |= 0x02000000;    // Turn on WS_EX_COMPOSITED
                return cp;
            }
        }

But unfortunately it will draw only thing drawn with Graphics object (or the internal controls). That's why I would like to render my XNA scene to Graphics object. Is there any way for that?

I have tried:

Every idea failed. Is there anything else?

Actually, Rendering to Texture is OK. Just rembember to call:

GraphicsDevice.SetRenderTarget(null);

Before you access data from it
