hello
I say first that this code works with windowsFormApplication, but no work with wpf, help me please

 
namespace WpfApplication22
{
public partial class App : Application
{
 

[DllImport("user32.dll", CharSet = CharSet.Auto)]
static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);
 
private const int APPCOMMAND_XXX = 0x80000;
 
private void MetodoMute(object sender, EventArgs e)
// Mute
        {
            SendMessageW(this.Handle, WM_APPCOMMAND, this.Handle,
                (IntPtr)APPCOMMAND_xxx);
 
        }
}
}

when I use:
        private void button4_Click(object sender, RoutedEventArgs e)
        {
            App x = new App();
            x.MetodoMute(new WindowInteropHelper(this).Handle);
       
        }

not works, It's launch exception:
"Eccezione non gestita di tipo 'System.InvalidOperationException' in PresentationFramework.dll

Informazioni aggiuntive: Impossibile creare più di un'istanza System.Windows.Application nello stesso AppDomain."



how do I call a method written in App.xaml.cs from another window?
