c# - Using INotifyChanged on DataContracts -

I am trying to isolate actual service data with the functionality of the service and therefore return data as data contract The one that holds many properties (data members) is generated by using the client code svcutil / edb which also generates the INotifyPropertyChanged implementation for the proxy code. As far as my tests have been revealed, that code has not implemented the event changing the property for changes on the server. In addition, receiving a property, the value of the property is returned only when the data contract proxy is received.

Actually, what I found here:

(server side)

  [service contact] Public interface IControllerService {[OperationContract] DataModel GetDataModel (); } [DataContract] Public class data module: INotifyPropertyChanged {Private string _State; [Database] Public String State {Set {if (_state! = Value) {_state = value; OnPropertyChanged ("State"); }} Get {return_state; }} Private Event PropertyChangedEventHandler PropertyChanged; [Operation Contract] Protected Virtual Vide On Peacetime Chengalated (String Properties) {If (Property Change = empty) contact has changed (this new Change of Property Event (Property name)); }}  

(client side)

  Private Zero Test () {controller service client client = new controller service client (); DataModel Model = Client GateData model (); Model.PropertyChanged + = New System. ComportModel.Property ChangesEventHandler (Datamodel Change); Console.WriteLine (model.State); // is called something that forces the server to change the data model // output remains on the same console. WrightLine (model.State); } Private Zero DataModal changed (Object Sender, System.ComponentModel.PropertyChangedEventArgs e) {// This method is sometimes not called for server-side change}  

I hope That the data contract acts as a proxy transparent proxy in the data contract of the server but it is completely unbounding.

Thanks in advance, cheers,

WCF does not make server side objects a wizard. It only defines the methods of your call in the service service and gives data to you. There is no other communication channel besides this.

So in your scenario you will need duplex service (see :) which will call the client manually with any changes to the server.
