Всем привет.
Недавно начал работать с системой на Silverlight 5.
На сегодня все обращения к базе данных происходят асинхронно через WCF
Ниже пример кода.
Вопрос , можно ли из обратиться к WCFсервису синхронно для последующего binding к гриду в UI.
Спасибо.
--------------------------



[ServiceContract]
public interface IMadicineService
{
[OperationContract(AsyncPattern = true)]
IAsyncResult BeginGetPaticipationTypesAsync(AsyncCallback callback, Object state);

List<DIC_ParticipationTypeMFPercent> EndGetPaticipationTypesAsync(IAsyncResult result);
}


public class MadicineService : IMadicineService
{

public IAsyncResult BeginGetPaticipationTypesAsync(AsyncCallback callback, object state)
{
List<DIC_ParticipationTypeMFPercent> madList = EntitiesFacade.GetPaticipationTypes();
return AsyncOperationHelper.BeginOperationAsync(madList, callback, state);
}

public List<DIC_ParticipationTypeMFPercent> EndGetPaticipationTypesAsync(IAsyncResult result)
{
return AsyncOperationHelper.EndOperationAsync<List<DIC_ParticipationTypeMFPercent>>(result);
}

}


----------------------------



public void GetParticipationTypes()
{
IMadicineService proxy = base.FactoryHelper.CreateChannel<IMadicineService>(new Util.ConfirmationChannelFactory<IMadicineService>());
proxy.BeginGetPaticipationTypesAsync(GetAllParticipationTypesCallback, proxy);
}

public void GetAllParticipationTypesCallback(IAsyncResult result)
{
ICommunicationObject channel = null;
try
{
channel = result.AsyncState as ICommunicationObject;
if (FactoryHelper.IsActive(channel) == false)
{
return;
}

List<DIC_ParticipationTypeMFPercent> Typeslist = ((IMadicineService)result.AsyncState).EndGetPaticipationTypesAsync(result);


}
catch (Exception ex)
{
RaiseOnDataLoadErrorOccured();
ExceptionHandler.Handle("hjkhjkh" + "\r" + ex.Message);
}
finally
{
this.FactoryHelper.DestroyChannel(channel);
}
}

Спасибо.
Нашел пример , если кому интересно
