  15. 15. Die Demo Kommt jetzt …(c) 2011 schrempp edv GmbH
  16. 16. Das Fazit I Sehr viel aufwändigere Entwicklung der Infrastruktur als gedacht Enorm viele Möglichkeiten (zur Fehlentscheidung) Mut zur „zweitbesten“ Lösung Steile Lernkurve für (Forms-) Entwickler Umstellung nur sinnvoll, wenn Anwendungs- und Validierungslogik auf Datenbank liegt Lange Koexistenz von WPF und Forms(c) 2011 schrempp edv GmbH
  17. 17. Das Fazit II Bisher keine unlösbaren Probleme 80% der Forms-Entwicklungsgeschwindigkeit wurden erreicht Enormer Motivationsschub für Entwickler(c) 2011 schrempp edv GmbH
