Catch-all error handling on application level?

Question

I have a WPF form with a couple of buttons, and for each button I have error handling code:

try {bla bla} 
catch(Exception e){
  more bla
}

Add this to you Global.asax:

protected void Application_Error(object sender, EventArgs e) {
    Exception currentException = Server.GetLastError();

    // your handling code goes here ...

    Server.ClearError();
}
