Warum kann DataContractSerializer Entity nicht in Plugins serialisieren, die in der CRM-Sandbox-Isolierung registriert sind?

Question

Kontext

Ich möchte Entity (EntityCollection) in einem Plugin, das CRM in Sandbox-Isolationsmodus 2016. die Ausnahme Siehe unten registriert serialisiert werden.

Frage

Genau das, was diese Klasse versucht zu tun, was nicht in Sandbox Isolation erlaubt? (Ich frage das, in der Hoffnung, wird das Verständnis zu einer Vermeidung des Problems/Trick/Hack führen. Ich möchte nicht benutzerdefinierte XML-Serialisierung-Code schreiben, weder benutzerdefinierte POCO-s erstellen und die Attribute kopieren.)

Sandbox-Plugins fehlen Berechtigungen nicht-öffentliche Mitglieder zu serialisiert (Refection erfordert vollständige Code-Vertrauen). Wenn Sie also nicht vor Ort sind, wäre die einzige Option, benutzerdefinierte POCO mit öffentlichen Mitgliedern zu haben und das Objekt zu serialisieren.
