************** JIT-Debuggen **************
Um das JIT-Debuggen (Just-In-Time) zu aktivieren, muss in der
Konfigurationsdatei der Anwendung oder des Computers
(machine.config) der jitDebugging-Wert im Abschnitt system.windows.forms festgelegt werden.
Die Anwendung muss mit aktiviertem Debuggen kompiliert werden.

Zum Beispiel:

<configuration>
    <system.windows.forms jitDebugging="true" />  
</configuration>

Wenn das JIT-Debuggen aktiviert ist, werden alle nicht behandelten
Ausnahmen an den JIT-Debugger gesendet, der auf dem
Computer registriert ist, und nicht in diesem Dialogfeld behandelt.
