I am not using "using" statement, the code looks like this:
partial class HeimdallClientService : ServiceBase
{
ServiceHost m_HmdlService;
public HeimdallClientService()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
StartService();
}
protected override void OnStop()
{
StopService();
}
protected override void OnPause()
{
StopService();
}
protected override void OnContinue()
{
StartService();
}
public static void Main()
{
ServiceBase.Run(new HeimdallClientService());
}
void StartService()
{
if (m_HmdlService != null)
m_HmdlService.Close();
m_HmdlService = new ServiceHost(typeof(HeimdallService));
m_HmdlService.Open();
}
void StopService()
{
if (m_HmdlService != null)
{
m_HmdlService.Close();
m_HmdlService = null;
}
}
}
Thanks.
From the exception you've shown, I suspect you are coding with "using"
when accessing the WCF generated proxy, right?
[CommunicationObjectFaultedException: The communication object,
System.ServiceModel.Channels.ServiceChannel, cannot be used for
communication because it is in the Faulted state.]
If so, then change the code to look like this:
Proxy c = new Proxy()
try
{
c.CallMethod();
}
finally
{
try { c.Close(); }
catch(Exception) { c.Abort(); }
}
The original exception will bubble up and will tell you what caused
the error.

Console client (which doesn't throw exception) does have identical
configuration.
Thanks.
Details on the exception would be useful, like stack trace, message
and
any inner exception involved.

Hi
I changed from XP to Vista and now when my web client call service
(WCF)
hosted by windows service I get CommunicationObjectFaultedException
(it
did work fine under the XP). Service is using wsHttpBinding. I
created
a
console client to call same service and that works without any
problems.
Anyone with same/similar problem?
