System.ServiceModel.CommunicationObjectFaultedException

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :JQuery
 

Hello,

I have a self-hosted WF service installed and running as a Windows service.  No issues with the service as such but there are times when the service fails to read from the queue (MSMQ endpoint).  This happens at random.  This is a long running service that runs for about 18 hours.  The service gets called once daily to perform this long running task.  We have a scheduler that picks up new data from the DB and queues it, which then gets picked up by the WF service.  The service will be running fine for 2-3 days and then it will stop reading from the queue.  I end up having to go to the Services console and stopping and then starting this service.

When I stop the service from the console, it throws an error that the service could not be stopped.  It stops at the second attempt.  Looking at the event log, I see this:

 

Failed to stop service. System.ServiceModel.CommunicationObjectFaultedException: The communication object, System.ServiceModel.Activities.WorkflowServiceHost, cannot be used for communication because it is in the Faulted state.

I've got a very, very simple WCF service. I'm hosting on Windows 08 with IIS7.

Problem with DuplexChannelFactory(System.ServiceModel.InstanceContext, System.ServiceModel.Descripti

  
I have derived a class from DuplexChannelFactory, and one of the constructors of the derived class takes System.ServiceModel.InstanceContext and System.ServiceModel.Description.ServiceEndpoint arguments. I simply pass them down to the base DuplexChannelFactory class, e.g.: public DerivedDuplexChannelFactory(System.ServiceModel.InstanceContext instanceContext, System.ServiceModel.Description.ServiceEndpoint endPoint) : base(instanceContext, endPoint) {} The problem I am running into that I get timeout exceptions when trying to callback the client during a service call, e.g.: Client subscribes to Service Client calls some Service method, during which call the Service will callback to the client Before I go further, if I call down to a different base constructor of DuplexChannelFactory, things work perfectly, e.g.: public DerivedDuplexChannelFactory(System.ServiceModel.InstanceContext instanceContext, System.ServiceModel.Description.ServiceEndpoint endPoint) : base(instanceContext, endPoint.Binding, endPoint.Address) {} If I use the former, I get the following exception: "This request operation sent to http://schemas.microsoft.com/2005/12/ServiceModel/Addressing/Anonymous did not receive a reply within the configured timeout (00:00:59.9820000). The time allotted to this operation may have been a portion of a longer timeout. This may be because the service is still pr

Placing ..... configuration information in a config file other than app.config

  
Hi, I'm sorry if this question has been asked/answered before on this forum. I have searched both here and on the web in general, but to no avail as yet... I am running VS2010 and .Net 4, so in theory have all the latest versions of everything at my disposal. I have an executable a.exe. This downcalls into a dll b.dll. b.dll wants to send an MSMQ message using WCF. For cleanness (a.exe is a generic service and knows nothing about WCF) I want to define the client endpoint in b.dll.config. However I am finding that WCF is insisting that the information is held in a.exe.config. The exact problem is that when I create my proxy (i.e. the class which derives from ClientBase<T>), I get the message Could not find endpoint element with name 'XXX' and contract 'YYY' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element. From what I have seen I have just described an extremely common problem that people have had with WCF over the years. My questions is basically to find out, given that I have WCF 4 at my disposal, whether there is now a standard approach to this scenario? Things I have tried so far: The obvious one...putting all my config info in a.exe.config. When I do this, everything works file, so I

Sudden Error: Could not load type System.ServiceModel.Activation.HttpModule - Urgent Help Please

  
hi,

I have a windows 7 machine with IIS 7. I was hosting WCF services on IIS normally and i had a couple of services running.
Suddenly (i honestly did not do any configuration changes on my machine) all these services stopped working. When i try to browse the .svc file i get the following error:


"Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'"

Just in case this information is helpful, all these services are running on the basicHttpBinding.

Please help!

System.ServiceModel.EndpointNotFoundException :

  

 

Hi,

I developed a WCF service with wsDualHttpBinding for a duplex communication. It is fine inside my computer.

With a client outside of the network, we have the following error : 

<ExceptionString>System.ServiceModel.EndpointNotFoundException: There was no channel that could accept the message with action 'http://schemas.xmlsoap.org/ws/2005/02/rm/CreateSequence'.</ExceptionString>.

I have set security to None.

Have you any idea ?

 

Thanks


 


Error when expanding datasources: Could not load System.ServiceModel

  

I am not sure if this is the right  forum, so let me know if I need to post elsewhere.

I am developing a standard ASMX web service for use with WPF/Silverlight applications (as well as other apps).  

However, when I create a new .NET 4 WPF or Silverlight application and add a service reference to my ASMX (not SVC), it lists all of the methods in the datasource pane fine, but when I try to show the contents, I get an error:

Could not load file or assembly 'System.ServiceModel, Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.  The system cannot find the file specified.

Is there something in the service configuration that I need to do, or is there something wrong with my web service?   In .NET 3.5 I do not get an error, but it doesn't show me the contents of the data sources either.  

Anyone have any ideas?
