Ich versuche, eine einfache MVC App zu erstellen, um Daten in eine Datenbank mit AJAX Post-Methode einfügen und bekomme einen unbehandelten Ausnahmefehler. Ich habe den Code so strukturiert, dass er mit der Tutorial-Seite identisch ist. Daher habe ich Probleme, herauszufinden, woher der Fehler kommt. Nicht sicher, ob ich möglicherweise die SQL-Verbindung ändern muss. Jede Hilfe wird geschätzt. Vielen Dank!ASP.NET MVC jQuery Beitrag Fehler

Ich denke, Sie haben keine AddEmployee Ansicht an der richtigen Stelle. Es sollte im Ordner "Views \ Home" abgelegt werden. – thisisbobbs
Arbeitete perfekt! Es scheint nicht, meine Datenbank zu aktualisieren, sobald 'Save' btn angeklickt wird, also arbeite ich jetzt an dem Debuggen. Das hat wahrscheinlich mehr mit meiner Verbindungszeichenfolge zu tun. Vielen Dank!! – AndrewC10
