Hi there

EDIT : THIS IS FIXED IN THE MOST CURRENT VERSION.

I just discovered that if I add an enum to my entity, WCF serialization breaks. Strangely enough, XML write/read within a unit tests works just fine.

//this is an entity
public partial class TicketEntity
{
  public TicketStatus Status
  {
    get { return TicketStatus.Pending; }
    set { /* ignore */ }
  }
}

public enum TicketStatus
{

  [EnumMember]
  [XmlEnum("0")]    
  Undefined = 0,


  [EnumMember]
  [XmlEnum("1")]   
  Pending = 1
}

As soon as I add the _XmlIgnore _attribute to the property, everything works just fine. I saw an older thread regarding the issue, which ended with the note that this would be fixed with 2.5, but it appears there's still an issue.

Notes:

• Adding the _XMLEnum _attribute seems to be ignored by LLBLGen - the _WriteXml _method serializes the string representation of the enum value (e.g. "[i]Pending[/i]"). Removing the attribute does not help Runtime: LLBLGen 2.5.0.0 (Adapter) / .NET 3.5

...this is currently not an issue for me, as the enum is a convenience property that I don't want to serialize anyway, but it might be worth having a look.

Cheers, Philipp

What's the exact build number of the runtime lib? As there were some fixes in this area in december, could you check if you have the latest build?
