  Title=”WCFAppVisualHost” Height=”383″ Width=”680″ Closing=”OnClose” StateChanged=”OnStateChanged” IsVisibleChanged=”OnIsVisibleChanged”

{     // initialise code here
    m_notifyIcon = new System.Windows.Forms.NotifyIcon();

void Method()
{
  // assuming string[] strings;
  Action stringAction = delegate(string stringParam)
