I fixed the error using the Dispatcher class as a mutex:

void Cam_NewFrame(object sender, NewFrameEventArgs eventArgs)
    {

        System.Drawing.Image imgforms = (Bitmap)eventArgs.Frame.Clone(); 

        BitmapImage bi = new BitmapImage(); 
        bi.BeginInit(); 

        MemoryStream ms = new MemoryStream(); 
        imgforms.Save(ms, ImageFormat.Bmp); 
        ms.Seek(0, SeekOrigin.Begin); 

        bi.StreamSource = ms; 
        bi.EndInit();

        //Using the freeze function to avoid cross thread operations 
        bi.Freeze();

        //Calling the UI thread using the Dispatcher to update the 'Image' WPF control         
        Dispatcher.BeginInvoke(new ThreadStart(delegate
        {
            frameholder.Source = bi; /*frameholder is the name of the 'Image' WPF control*/
        }));     

    }

Now it runs as expected and I get good performance without any drop in the fps.
