Duplex communication and calling clients from outside the hosted service

Posted By:      Posted Date: September 02, 2010    Points: 0   Category :WCF
Hey,   I am currently building an interface between two applications: One that hosts a WCF service and receives external input (e.g. from a sensory system) and another which subscribes to updates sent by the first.   It is quite easy to call back to the client if I create a ServiceHost and provide it with an instance of my service (using ServiceHost.SingletonInstance). However, if I use a PerSession instance mode, how is it possible to call the clients when I receive an updated from the external sensory system?   Thank you for your time!   Cheers, Till

VS2005 calling VS2010 asmx service returns empty string


Anyone have any experience with this?

We are using VS 2005 for the front end, and vs 2010 for the web services part (asmx), not wcf yet.


Web service works just like the vs2005 when run locally, no problems.


Connecting to it from a test app returns an empty string. Connecting to a 2005 app doesn't!

Anyone run into this before or have a suggestion? Surely vs 2005 can connect to web services from a later version?






Cannot get service reference for Net.tcp service hosted in IIS7

HiI've got a service that I want to host in IIS7. The service runs over net.tcp (currently without security), but I am unable to create a service reference to it, or call it, using the net.tcp protocol. My event log is populated with lots of errors related to ASP.NET and System.ServiceModel, relevant services are installed and running (net.tcp port sharing service and net.tcp listener adapter).O/S : Window7 RTMDevStudio: 2008I publish the webservice to IIS7 and I get a valid page when navigating to the published .svc file (which tells me to use svtutil.exe and point it at the net.tcp endpoint).For that, I get this error :    The message could not be dispatched because the service at the endpoint address 'net.tcp://gedm-desktop.profiledc01.appdevelop.local/ManageAVMEP/ManageAVMAgent.svc/mex' is unavailable for the protocol of the address.Googling the problem leads me down several blind alleys :(I cannot determine what is causing the net.tcp listener to keep stopping? Everything is fine if I use the wsHttpBinding.Any tips or pointers to a course of action would be appreciated.ThanksGed My event log is full of errors (here is a sample) :-------An error occurred while trying to listen for the URL '/LM/W3SVC/1/ROOT/ManageAVMEP'. This worker process will be terminated. Sender Information: net.tcp Exception: System.ServiceModel.WasHos

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

Calling an asp.net web service from jQuery

As I have post it in earlier post that jQuery is one of most popular JavaScript library in the world amongst web developers Lets take a example calling ASP.NET web service with jQuery . You will see at the end of the example that how easy it is to call a web service from the jQuery. Let's create a simple Hello World web service. Go to your project right click->Add -> New Item and select web service and add a web service like following.   Now modify the code of web service like following. [WebService(Namespace = "http://tempuri.org/")][WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)][System.ComponentModel.ToolboxItem(false)]// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. [System.Web.Script.Services.ScriptService]public class HelloWorld : System.Web.Services.WebService{ [WebMethod] public string PrintMessage() { return "Hello World..This is from webservice"; }} Here please make sure that [System.Web.Script.Services.ScriptService] is un commented because this attribute is responsible for allowing web service to be called by Client side scripts. Now to call this  web service from jquery we have to include jQuery Js like following. I am already having in my project so i don't need to include in project just need to add script tag like following. <script type="t

calling a web service on a remote server from an ASPX page

hi, I want to call a web service on a remote server. I've done "add web reference" in my project, and VS2005 has created the .discomap and .WSDL in the App_Web_Reference folder. When I try add the namespace representing the web server (the name I created when I added the web reference) by "using XXXXX;" the code does not compile because XXXXX is not defined. Have I missed any steps? thanks, -me

While calling Web service gets exception "The request failed with HTTP status 401: Unauthorized"

Hi All, I created a ASP.NET web service, which was hosted on default visual studioserver, and on excecution of webservice it run .exe file which in turn update xml file. Now i hosted this webservice on IIS 6.0 server, and when i run the service, itfails to execute the exe.When i run it on debug mode, i never get any exception.Code...public string HelloWorld()    {        Process myProcess = new Process();        try        {            myProcess.StartInfo.UseShellExecute = false;            // You can start any process,             myProcess.StartInfo.FileName = @"E:\Projects\some.exe";            myProcess.StartInfo.CreateNoWindow = true;            myProcess.Start();            myProcess.Close();            myProcess.Dispose();            return "Suceess";         }&n

calling a web service on a remote server from a ASPX page (web site project VS2005)

HI,I am maintaining a web site project in VS2005 and have to call a new web service on a remote server. I've done add web reference, and created the .wsdl and .discomap files in the app_webReference folder.  When I try to create a object representing the web service in the code ( wsnamespace.serviceName ws = new wsnamespce.serviceName(); ) the code wouldn't compile.The web site project is already calling other web services. When I right click on the type representing the web service and "go to definition" it takes me to a proxy class (derived from of course SoapHttpClientProtocol) in the metadata. I think this is what's missing for  the new web service i'm trying to call. Have I missed any steps?Thanks in advance.-me

Error calling WCF service that is returning list.".Debugging resource strings are unavailable ......

Ok.this is just making me frustrated... Here is step by step of what I am trying to do (& not able to) 1. I am calling WCF service hosted in a SharePoint 2010 site from a silverlight app in same domain (So no cross doman I guess). 2. I use Linq to Sharepoint for querying the DB. 3. I am having a list "machines" in Sharepoint 2010 that is having a lookup column from Other list called "part" 4. My WCF method GetAllMachines() works perfectly well when it skips the lookup column "partname" & returns List of type machineitem. 5. But problem occurs when I add machineitemobject.parts.partsname in my Linq to Sharepoint query . My service gives the error not found Async_ExceptionOccurred] Arguments: Debugging resource strings are unavailable." 6. Note that return type of my Method is List<machinesitem> 7. The point to note here is that I use SPMETAL tool to generate the LINQ class that maps the lists . So When I try to query the lookup column it tries to add List item of the type class & that is what causing the error. Is it because I am not using datacontract in my service (but it returns the strings & all private members of machines list e.g. name,title etc) Is it making the attribute Serialisable will solve the error ??? I am kind of lost in it ...Plss help!!   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);

Workflow Service not calling workflow in another project

I have a windows workflow service 4.0 that calls a workflow located in another project (i.e. another assembly). I have created a project reference in my workflow service project to the workflow in the other assembly. I have set a breakpoint in the workflow service receive activity and this breakpoint is hit. Next I step into the next activity which is an activity located in another project and the debugger does not work. Also the other workflow is sending an email.  It appears that the other workflow is not being called because I never receive an email from the workflow in the other project.   Any help is greatly appreciated.

Calling one endpoint from another endpoint in the same service

Hi, I have a WCF service host Im hosting in IIS that defines a few services and one of those services has a number of endpoints. The endpoints that belong to the same service are there to let me specify different contracts and they all use the same binding and behaviour. For the most part it works fine until a specific situation occurs: The service gets stuck when one of the endpoints tries to make a call to another endpoint in the same service. Consider the following example: <service behaviorConfiguration="GeneralServiceBehavior" name="Base"> <endpoint address="/Addresses" binding="wsHttpBinding" bindingConfiguration="wsHttpBindingConfig" contract="CommonObjects.IAddresss" /> <endpoint address="/Attachments" binding="wsHttpBinding" bindingConfiguration="wsHttpBindingConfig" contract="CommonObjects.IAttachments" /> </service> In the example above if a call is made from IAttachments implementor back to this service to access the IAddress endpoint I get stuck in what seems to be a deadlock until I get a timeout on the calling thread and then I see the call come through to the IAddress endpoint, but at that point its already too late as the channel is closed. I have looked at the InstanceContext and ConcurrencyMode. This particular servic

Exposing WCF Service for multiple clients with the feature of multiple database support

WCF Service hosted in IIS 6 failing on idle timeout and does not restart

I've got a WCF service hosted in IIS 6 with its own application pool.  The application pool is running under a domain service account.  It appears that the application pool's idle shutdown setting is killing WCF service and subsequent requests to the WCF service get an exception as listed below I can only access after I browse to the .svc page in order to get it working again.   I've went through the svc tracing and able to see where the ServiceHost closes down. I have tried various session management techniques with no result. I haven't read anything about having to disable the idle timeout in IIS 6 when hosting a WCF service, and I suspect that there shouldn't be any need to.   Can anyone provide any insight into why this is happening?   ******************* My client exception ******************* Test method **********  threw exception:  System.ServiceModel.ProtocolException: The content type text/html; charset=utf-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 1024 bytes of the response were: '<html>     <head>         <title>Runtime Error</title>
