Hello,
I am happily using Castle's WcfFacility. From Monorail I know the handy concept of Rescues - consumer friendly results that often, but not necessarily, contain Data about what went wrong.
I am creating a Silverlight application right now, doing quite a few WCF service calls. All these request return an implementation of
public class ServiceResponse
{
private string _messageToUser = string.Empty;
private ActionResult _result = ActionResult.Success;
public ActionResult Result // Success, Failure, Timeout
{
get { return _result; }
set { _result = value; }
}
public string MessageToUser
{
get { return _messageToUser; }
set { _messageToUser = value; }
}
}
public abstract class ServiceResponse<TResponseData> : ServiceResponse
{
public TResponseData Data { get; set; }
}
If the service has trouble responding the right way, I would want the thrown Exception to be intercepted and converted to the expected implementation. base on the thrown exception, I would want to pass on a nice message.
here is how one of the service methods looks like:
[Transaction(TransactionMode.Requires)]
public virtual SaveResponse InsertOrUpdate(WarehouseDto dto)
{
var w = dto.Id > 0
? _dao.GetById(dto.Id)
: new Warehouse();
w.Name = dto.Name;
_dao.SaveOrUpdate(w);
return new SaveResponse
{
Data = new InsertData
{
Id = w.Id
}
};
}
I need the thrown Exception for the Transaction to be rolled back, so i cannot actually catch it and return something else.
Any ideas, where I could hook in?
