Question

I have a collection class that I have decorated with a CollectionDataContract. The collection class also has a property on the class that I would like to be passed to the service client. I have tried adding [DataMember] to that property but it didn’t add it to the class in the client when I updated.

Any WCF experts out there have any help to offer?

UPD: Thanks, for your comment, Jeff. Here is a summary here of a non generic class. A full generic solution can be found in a new post in my blog: http://borismod.blogspot.com/2009/06/v2-wcf-collectiondatacontract-and.html

 [DataContract(IsReference = true)]     public class EntityCollectionWorkaround : ICollection      {          #region Constructor         public EntityCollectionWorkaround()         {             Entities = new List();         }          #endregion          [DataMember]         public int AdditionalProperty { get; set; }          [DataMember]         public List Entities { get; set; }          #region ICollection Members           // Implement here members of ICollection by wrapping Entities methods         #endregion          #region IEnumerable Members           // Implement here members of IIEnumerable by wrapping Entities methods         #endregion      }
