Ich hatte heute einen Fehler nach dem ich länger (naja “länger” ist relativ) suchen musste, weil es dazu weder auf Live noch auf Google passende Ergebnisse gab. Deshalb hier die Lösung:
Falls man versucht, eine .NET 3.5 SP1 Anwendung, die einen WCF Dienst aufruft, auf einem System ohne SP1 laufen zu lassen, kann es zu folgender Exception kommen:
System.Reflection.CustomAttributeFormatException: 'IsReference' property specified was not found. ---> System.NullReferenceException: Object reference not set to an instance of an object.
