Yes I was, by creating the class as you suggested.

Because the return type of InvokeServerMethod is Object, .NET's serialization behavior may not be as clean.  Were you able to get it working?

Thanks for your reply

I thought that Arrays were 'WCF-serializable' by default. Or perhaps is DevForce doing something which prevents Arrays working 'out of the box'?

Yes, but in this case, .NET is having difficulty serializing the value.  Try using the typed list below instead of an array.  It has most of the serialziation markup for .NET to discover.  (You may also have success just using one of the other .NET collection classes.) 
 
  [System.Runtime.Serialization.DataContract]
  public class GuidList : List<Guid>, IKnownType {
    public GuidList() : base() {}
  }
 
In the worst case, you would create your own custom class, use the [DataContract] attribute on the class, add the IKnownType marker interface, and mark each serializable property with the [DataMember] attribute.

Hi

I want to return an Array (of Guid) using InvokeServerMethodAsync but the call fails with the exception "The remote server returned an error: NotFound."

If I return a single Guid, it works fine.

Is it possible to return an Array?
