How to setup a ReceiveReply activity to receive the result of a WCF service operation?

Posted By:      Posted Date: October 25, 2010    Points: 0   Category :Windows Application

I already figured out what I have to do to send a WCF message to a WCF service developed with .NET, but I could not get the result back to the workflow. I need to know what I have to do to get that result. 

I have a very simple test WCF service with following contract:

[ServiceContract(Namespace = http://www.juergen-bayer.net/samples/wcf)]
public interface IDemoService
  long Add(int value1, int value2);

The client application uses a workflow with a Send and a ReceiveReply activity. The WCF endpoint is configured in the config file:

   name="BasicHttpBinding_IDemoService" />

The Send activity is configured like follows:

Action="http://www.juergen-bayer.net/samples/wcf/IDemoService/Add" => This would also be the default value in my case

The parameters of the WCF message are placed in the content:

Workflow Service 4.0 with One Way Receive activity will not get fired when called by a console based

Workflow Service 4.0 with One Way Receive activity will not get fired when called by a console based client application. This service does get called when there's the default ReceiveRequest coupled with a SendReply activity in the service. However deleting the ReceiveRequest and SendReply Activities and replacing it with a one way Receive Activity causes the Workflow 4.0 Service to not get called.

How add Operation Behavior on a Receive Activity?

A lengthy operation in an ASP.NET web service


I've built an ASP.NET web service with .NET 2.0 (an asmx file). I invoke a web service method using Ajax. The method takes a substantial amount of time to execute (5 minutes to 1 hour). I believe it's not a good idea to "hang" the web request for so long.
I'm wondering if the web service method could spawn an additional process which in turn would execute the lengthy operation and notify the web service once the operation is completed.
Are there any good practices regarding this kind of functionality?

CRUD Operation should be Part of BO or Service/Manager Classes?



I am developing an application which has a general structure similar to what Scott has described at http://nhibernateasp.codeplex.com

Thanks to Scott for developing such a nice architecture which can be used for most of the projects!

It uses Service Layer which contains service classes (like Product Service) which actually talk to the repository layer (ProductRepository) and these service classes are responsible for CRUD operations while the BO (Product) contains just the data and the validation methods.

As I have read, in OO design, you should design a class which contain both data and behavior, in which case, the BO (Product) should be responsible for doing its own CRUD and it should not be a responsibility of Service classes.

Which approach you think is better design and what could be the reasons?

Any help is this regard is appreiciated.




Net Framework 1.0 Error 1904 during setup mscoree.dll H-result 2146232576

I cleaned off all my .Net framework files with the .Net framework cleaner. I then started at 3.5, installed it, went well, installed 3.0, went well, installed 2.0, went well, installed 1.1, went well, then, tried to install 1.0 redistribution package for my windows xp home and it stopped at almost the very end saying ERROR installing 1.0 ERROR 1904 system32\mscoree.dll failed to register. H-result 2146232576. I tried renaming it and installing the 1.0 again but still get the same error. i tried using the IGNORE option, it said it installed but i know the mscoree.dll isn't working. i used the installer cleanup tool also to no avail. i deleted the URTTemp folder and tried a reinstall. This didn't work either. Anyone know what I might can do to get this corrected? I have not done anything myself in the registry. I have used RegCure and registry mechanic but Net Framework 1.0 still gave the error when I tried to install. Any help appreciated. I did read something about 1.1, 2.0,3.0 or 3.5 might have a newer mscoree.dll file and that night be why I can't register the one I have. I need the 1.0 version 3705 though as one of my programs uses it. Also, i am now not able to put any of the updates on my computer. it downloads them but they fail to install. Example, net framework 2.o service pack 2, net framework 3.5 service pack 1, and net framework 3.5 family update. Thanks....

Service Operation - Get proper data when browsing the service, but not when calling the service from

Hello, I recently implemented a service operation in an attempt to pass some filter parameters to a data service (a user guid and an organization, actually, for impersonation of a user on the service's call to the application). I successfully added the service operation to the data service, and I can browse the service and see the data filtered as I expected. However, when I call the service operation from the Silverlight client, I don't get any results, even though I should. Am I missing something? Code below if it's helpful. Thanks! Service Operation Definition: [WebGet] public IEnumerable<opportunity> filteredopps(string userid, string org) { /*Define the connection with the impersonated user*/ CrmConnection crmc = CrmConnection.Parse("Authentication Type=Passport; Server=https://" + org + ".crm.dynamics.com/" + org + "; User ID=myuser; Password=mypassword; Device ID=mydeviceid; Device Password=mydevicepassword"); crmc.ImpersonatedUser = new Guid(userid); var crmOnline = new DataContext(crmc); List<opportunity> uplist = new List<opportunity>(); crmOnline.UsingService(service => { var query = from o in crmOnline.opportunityopportunities select o; foreach (opportunity thisopp in query) { uplist.Add(thisopp);

To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the s

The following error is issued following 10 minutes of system inactivity: An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail. ---> System.ServiceModel.FaultException: The message could not be processed. This is most likely because the action 'http://tempuri.org/IParticipant/SearchParticipants' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding. Per the message, I tried changing the app config on the client from     receiveTimeout     ="00:10:00" to     receiveTimeout="10:00:00" but the change seems to have no impact.  What am I missing?

Service Operation with Joins between entities

Hello, I have a service operation that queries multiple entities in a data source using joins. However, I can't seem to get to the joined entity, either when browsing the data service in IE, or when consuming the data service in the silverlight client code. With this code in the data service operation method: var query = from o in crmOnline.opportunityopportunities join su in crmOnline.systemusers on o.ownerid.Value equals su.systemuserid select o; Should I not be able to view the data service in a browser and see the systemusers like this (the service operation takes two arguments, userid and org): http://localhost:6246/convoservice.svc/filteredresults?userid='22222222-f3sw-aahh-hy65-nn88dd3333ee'&org='testorg'/systemusers or to consume it in the client like this foreach (opportunity opp in response) { string name = opp.name; string ownername = opp.opportunity_owning_user.fullname; ... ? In either scenario, I'm not having success. When browsing the URL posted above, I get an http 400 "webpage cannot be found" error. I get a null reference exception in the client. Any help would be greatly appreciated! Web: http://invoc.net

How to setup Query Result Shaping for LinQ to SQL instead of Entity Framework?

Hi, I am new to this, and I am trying to implement a linq query similar to db.Genres.Include("Albums") command from mvc music store using my current DB setup. I realize that the tutorial mentions Checlking the "Include foreign key columns in the method" when creating the tables in ADO.NET, but if I am using LINQ to SQL classes, then how can I obtain the same effect. And how do I use db.Genres.Include("Albums") to simplify my life? Thanks

Wpf window, which contains result of every activity

Hi, In my application I rehost workflow designer. I have a few custom activity. Every activity has public property (bool) - result. In application, which rehosts workflow designer I would like to have menu button "Test". After the user presses this button, workflow should start once and user should see "Result window" (WPF window), which should contains every activity result. I'll add that I' using code from the book "Professional C# 4.0 and .NET 4" (http://media.wiley.com/product_ancillary/58/04705022/DOWNLOAD/502259%20Code%20CH44.zip). Has anyone any idea how to do this? It is possible or not?

Access is denied error thrown in "Setup Secure Session" activity


Could someone help me with the following issue, please?

System setup:
- Windows 2008 R2 server hosting both MVC2 web application and WCF service for it;
- users connect to the web application which gets all data from the WCF services;
- WCF services are resused by several other applications (WinForms based) which work fine and have never experienced any security related problems;
- MVC2 uses impersonation (<identity impersonate="true"/>) to connect to WCF services, so we have single security boundary for both web and winforms clients (which are out of scope of the problem);
- both MVC2 web application and WCF services share the same ASP.NET v4.0 DefaultAppPool application pool, running under NetworkService identity;
- all users, user PCs and servers belong to the same AD domain, which is a part of global corporate tree;
- all unhandled exceptions are automatically caught by the web application and forwarded to application developers' e-mail box;
- WCF binding setup in web application:

    <binding name="WSHttpBinding_BifrostServices" closeTimeout="00:10:00"
     openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"

Search server 2010 setup - error creating search service application

I am running in a very similar siutation as this post:

I am configuring a new Search Server 2010 production environment.

I used the search setup account to run the setup and run the SharePoint Products Configuration Wizard.

During the first run of the SharePoint configuration wizard (where the farm account and service applications are setup), the process failed because the search service application could not be created.  

Errors were encountered during the configuration of the Search Service Application.
System.Data.SqlClient.SqlException: User does not have permissiont to perform this action.

I was under the assumption that the setup account had securityadmin and dbcreator SQL Server roles.  However, this was not the case and I had them added.  My original thought was the setup failed because of this.  After those roles were added, I tried to recreate the search service application and I still get a failure.

I am pretty sure I have followed the prerequisites as prescribed by Microsoft in terms of account setup (
