MSMQ Recieve Activty fails in workflow hosted in Windows Service

Posted By:      Posted Date: October 28, 2010    Points: 0   Category :Windows Application


I am trying to implement a windows service hosted workflow service that polls from a message queue. The message queue is is populated by a separate windows service.

I followed the post below for my hosted workflow as it looked to be close to what I was trying to do.


Following the steps in the post I was able to get my service to work when the message body was a simple string and using the WCFTestClient.

I then changed the code to use a a custom .NET object as the Recieve parameter instead of the string. The class library in which the object is defined was added as a reference. The service that populates my queue uses the custom .NET object as the message body.

In this scenario, the service would run but only process a message from the queue if it was in the queue before the service started. Any new messages added are ignored and if I add the message after I start the queue it also does not get picked up.

My xamlx is below, followed by my app.config:

How to debug Windows Workflow when it is hosted by WCF Service ?



I have build a test solution in two parts :

1) WCF service which hosts a Windows Workflow (statemachine).

2) Console application which consumes the WCF Service.

It works well, but if I do a bad process, it crashes which is normal. Exemple : the client calls an event which is impossible to execute given the current state according to the workflow design. In this case, the client receives a WCF exception. This exception is masked, which is normal (an option has to be set in WCF side to enable exception transmission).

The problem is that, althought I launched the console application with the debugger, with the WCF service project, the debugger doesn't break on Workflow errors in WCF error side. (However, I saw that non-Workflow errors in WCF side are still stopped by the debugger)

How could I force the VS debugger to break on Workflow WCF errors ?

xamlx workflow service initialization hosted in IIS on net.msmq endpoint


Hi everyone,

I implemented xamlx workflow service. I need to implement code that will be called before the service is invoked. I host workflow service in IIS on net.msmq endpoint. I saw that global.asax does not help me. I searched internet and found that I could use public static void AppInitialize(); method in App_Code folder class but that does not work.

Can you give me some suggestion or send code sample that can be used for initialization of application in iis that hosts xamlx workflow services on netMsmq binding?

Question about WCF Service hosted in Windows Service

Hi, I have little experience with WCF and working on a projet that requires WCF Service instance to run 24x7. After searching for a solution and reading about WCF, I think if I host it under Windows Service I can have a single instance of WCF Service running 24x7. Is this correct? I just successfully ran the MSDN sample project that hosts CalculatorService in Windows Service. I realized that Windows Service cannot communicate with WCF Service it is hosting (I do not have any experience with writing Windows Service). I wrote a test function (public) in Windows Service and tried to call it from WCF Service but it did not appear in the Intellisense list. Is my assumption correct or is there a way to establish communication between Windows Service and its hosted WCF Service? Thanks. kr

Unable to call an asmx web service using windows authentication from a Service workflow

Hello, I need to use an existing asmx service from inside my service workflow and I am unable to call it. This asmx service is hosted in a web application with iis set to windows authentication, anonymous is not allowed. I need to send the authentication, only way seems too be using transport for basicHttpBindings. Every time I try to call the service I get an error saying that there is nothing listening to the url of the service generated automatically by VS when I added the Service Reference ? my web config <configuration> <configSections> </configSections> <system.web> <compilation debug="true" targetFramework="4.0" /> </system.web> <system.serviceModel> <protocolMapping> <add scheme="http" binding="wsHttpBinding" bindingConfiguration="WindowsCreds" /> </protocolMapping> <bindings> <basicHttpBinding> <binding name="UtilitiesSoap" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"

Hosted Designer fails to load workflow xaml that has InArguments with default values (xaml saved by

I have hosted the designer in our app. Using the hosted designer, workflows are saved as xaml to a database. When an end user wishes to edit a workflow the xaml is downloaded to a file and loaded into the designer via the .xaml file. The user can also associate assemblies with the workflow and there is a mechanism which makes sure that these assemblies are loaded into the appdomain and available. The problem we are hitting occurs when the top level activity (Sequence) has InArgument with default value. I create a simple Sequence, add InArguments (type of Int32 and String)  and set some default values. I save the workflow xaml to the database and close down the designer. When I wish to edit the workflow and try to load I get the following errors Could not find member '{clr-namespace:}_e905.argument3'. Could not find member '{clr-namespace:}_e905.argument1'. suggesting that some assembly/namespace missing. Here is the xaml I try to load: <Activity mc:Ignorable="sap" x:Class="{x:Null}" this:_e905.argument3="99" xmlns="http://schemas.microsoft.com/netfx/2009/xaml/activities" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:mva="clr-namespace:Microsoft.VisualBasic.Activities;assembly=System.Activities" xmlns:s="clr-namespace:System;assembly=mscorl

Suspend / Resume Instances within Workflow Service Host (in Windows Service)

We are hosting WF 4 worklfow instances within a Windows Service that uses the Workflow Service host container.   On the Windows Service OnStart we start the workflow service host (w/ multiple WCF endpoints such as start workflow instance, cancel workflow instance, poll workflow instance status, etc.) and these endpoints create or work on one or more long running workflow instances.     My question is, if a user attempts to stop the Windows Service while workflow instance(s) are running, what is the best way to manage this scenario.   Our inclination is to persist these workflows (using sql persistence) and then on the next start of the Windows Service, resume these workflow instances and allow them to continue to completion.    In OnStart, we have a handle to the Workflow Service host.    How can we iterate through all the active workflow instances in OnStop and then in OnStart, resume these after the workflow service host is opened and running?   Are there are any methods of managing this scenario?    Thanks

WCF hosted in a Windows Service, how to make calls to the WCF service from within the service host


I have a Windows service that I converted to a WCF service that I want to host in a Windows Service.  I need to do some specific tasks in the OnStart() and OnStop() just like I did when it was just a Windows service.  My original Windows service OnStart() is where I create the main worker thread.  So how do I make a call into my WCF service from within the hosting service? For example in the hosting service's OnStart() I do a host.Open() then I need to call a method in my WCF service but how?

TCP Error Code 10060 when attempting to access WCF Service hosted by WIndows Service from client run


Hello all,

We have a Framework 3.5 WCF Service which is in turn hosted in a Windows Service using Net.Tcp Binding. SvcUtil is used to generate the proxy which is used instead of a service reference in the client code. We are also using Tcp Port Sharing. The endpoint address is net.tcp://HostMachineName/MyServicePath. The service logs to the Event log and everything works perfectly on the same machine.

When attempting to run the client from a different machine we are getting TCP Error Code 10060 errors. Below is the error message:

System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://HostMachineName/MyServicePath. The connection attempt lasted for a time span of 00:00:20.8592415.

Has anyone encountered this problem? Also, client specs say no config files, so anything that wo

nettcpbinding with windows security in iis hosted service


Hi ,

I have hosted service in iis. How can i verify my service (transport mode)is using windows authentication for client.

when i use basichttpbinding and set clientCredentialType to windows, but iis with anonymous. When i browse svc, as expected i get error that secrurity setting of servcie needs windows but iis is configured as anonymous. Similar i see expected bheavior when service is configred for anonymous, but iis is configured for windows.

But when i use nettcpbiding, irrespective of what my iis setting is (windows/anonymous), if i configure service for windows and i browse svc file. I am always able to do to without any error. when service is configured for windows and iis for anonymous; shouldn't i get an error (as seen in case of basichttpbinding)

How to enable windows authentication for a RESTFul web service which is not hosted in IIS


I have created a WCF RESTFul webservice by following http://msdn.microsoft.com/en-us/library/dd203052.aspx. I am hosting my RESTful webservice in a window service (and not IIS) using the WebServiceHost class. 

Now I am struggling to get user's windows credentials in my web service methods. I looked at various code samples in forums for this. Almost all of them are hosting the service in IIS plus configuring  the service's settings using <system.serviceModel> tag.

I don't want to host my service in IIS plus as of now I haven't overridden any EndPoints, Behaviours etc in .config file.

I tried with below code in my window service's onstart method

WebServiceHost host = new WebServiceHost(typeof(MyService), new Uri(_serviceUrl));

ServiceAuthorizationBehavior myServiceBehavior = host.Description.Behaviors.Find<ServiceAuthorizationBehavior>();
myServiceBehavior.PrincipalPermissionMode = PrincipalPermissionMode.UseWindowsGroups;


After putting above code I queried ServiceSecurityContext.Current and System.Threading.Thread.CurrentPrincipal  my RESTFul's method but they are showing no sign of return

Web service call fails on Windows 7


I have a Windows application written in C# using .NET 2.0 and Visual Studio 2005. I develop on a Windows XP machine. The application makes web service calls over SSL. To support SSL, I have to install WSE 3.0 on the development machine.

When I run my app on an XP machine it works perfectly and makes web service calls to an SSL enabled web service after I set the following registry entry to a non-zero value:

DWORD Value = zero Value = nonzero
UseScsvForTls  Client sends Renego Info extension for TLS  protocol  Client sends SCSV for TLS  protocol



The problem occurs when I run the app on a Windows 7 machine. The web service call fails with the following error:


The underlying connection was closed: An unexpected error occurred on a send.-   at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request)

WCF REST webservice hosted in a windows service


Hi, I created a WCF REST service which had a method "Result":



public interface IService


   [OperationContract(Name =  "Result")]

   [WebGet(UriTemplate = "/")]

   string Result();


When I went to the default page http://localhost:portnumber/Service.svc it would display the string returned by Result().


I then wanted to host the WCF service in a Windows Service. The service is running fine and I can browse to the baseAddress. However in this setup it displays the default "You have created a service" page and doesn't execute the method returning the string.


I'm not even sure if this is possible. In summary is it possible to how a WCF REST service in a Windows Service and get it to respond to HTTP GET requests?


Can anybody suggest a solution?





Windows Server Backup fails when SQL VSS Writer service is running


Hello. On one of our SQL servers, we have SQL Server 2008 Express installed. Whenever is the "SQL Server VSS Driver" service running, backing up the computer with Windows Server Backup will always fail. If I stop SQL VSS writer service, then it the backup will finish successfully, although apparently backup of the SQL DBs is not consistent.


- backup is executed with "wbadmin start backup -allcritical -backuptarget:d: -vssfull -quiet"

- root of the SQL Server instance (and all DBs, trans. logs etc) are located on a volume E:

- once the backup command is executed, it's stuck on the creating volume shadow copies operation for several minutes, failing afterwards

- SQL VSS Writer has status 8 (failed), last error is "non-retryable"

- eventlog contains myriad of messages since the backup is started (SQL server has hundreds of DBs on it), with variations of these 3 repeating:

  a) SQLVDI: Loc=TriggerAbort. Desc=invoked. ErrorCode=(0). Process=1304. Thread=15788. Server. Instance=SQLEXPRESS. VD=Global\{A4C1E365-459A-4D41-B3D0-1A76DB8E56F6}517_SQLVDIMemoryName_0. Source: SQLVDI, EventID: 1. This is repeated numerous times, where thread id varies and number (517 in this case) in the VD identifier

  b) BACKUP failed to complete the command BACKUP DATABASE
