Ich habe einen Dienst, in der alle Methoden gut funktionieren mit einer Ausnahme berufen, die eine list<Module>WCF Test Client Fehler Fehler beim Service (beim Senden Entities Durch WCF)
Meine Module Class zurückgibt (juristische Person) ist wie folgt
[DataContract(IsReference = true)] //prevents Infinite loop
[KnownType(typeof(SubModule))]
public class ModuleMst
{
public ModuleMst()
{ }
[Key]
[DataMember]
public int moduleid { get; set; }
[StringLength(100)]
[DataMember]
public string modulename { get; set; }
[StringLength(1)]
[DataMember]
public string status { get; set; }
[DataMember]
public string crby { get; set; }
[DataMember]
public DateTime crdt { get; set; }
[DataMember]
public string modby { get; set; }
[DataMember]
public DateTime moddt { get; set; }
//[DataMember]
public virtual List<SubModule> SubModules { get; set; }
}
Die Ausnahme WcfTestClient zeigt als
An error occurred while receiving the HTTP response to http://localhost:8888/ArchService/. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

Die Ausnahme ist nicht sehr hilfreich.
Auch alle Bindungen schlagen mit dieser bestimmten Methode fehl.
Was habe ich vermisst?
EDIT
Es scheint, wie jede Methode, die eine Liste zurückzukehren versucht (wobei T eine beliebige Einheit sein kann) mit dem Fehler
Client-Konfiguration wie An existing connection was forcibly closed by the remote host

EDIT 4
Jetzt bin ich bestätigt, dass der Fehler auf aufgrund der Proxy von EF erstellt sind nicht serialisierbar als solche Nach diesem MSDN Artikel https://msdn.microsoft.com/en-us/library/ee705457(v=vs.100).aspx Und auch nach this SO Article
WCF/SOAP hat kein Problem mit Listen. Ich gehe davon aus, dass dies auf einen bestimmten Teil des DataContract zurückzuführen ist. Ich würde empfehlen, wenn möglich dem Dienst beizutreten, um die Ausnahmedetails auf der Dienstseite zu sehen. –
@Glen Thomas Das Lustige ist, dass ich ein Objekt des gleichen Typs zurückgeben kann. Das Problem passiert nur mit der Liste des genannten Typs !! – Deb
Wenn Sie das Ausnahmedetail bekommen können, können wir das viel schneller lösen –
