  • Debug Deserialization on Silverlight Client

    - by Andrew Garrison
    I'm working on a Silverlight client that interacts with a WCF web service. The Silverlight client and the WCF web service are using the same class library for their data entities that they are passing back and forth over the wire. I just added a new entity, and it's not being correctly deserialized on the Silverlight client. My question is, how can I debug the System.ServiceModel.ClientBase as it is deserializing an entity that it received from a WCF web service?

  • How to make sure web services are kept stable from one release to the next?

    - by Tor Hovland
    The company where I work is a software vendor with a suite of applications. There are also a number of web services, and of course they have to be kept stable even if the applications change. We haven't always succeeded with this, and sometimes a customer finds that a service is not behaving as before after upgrading. We now want to handle this better. In general, web services shouldn't change, and if they have to, at least we will know about it and document the change. But how do we ensure this? One idea is to compare the WSDL files with the previous versions at every release. That will make sure the interfaces don't change, but it won't detect that the behavior changes, for example if a bug is introduced in some common library. Another idea is to build up a suite of service tests, for example using soapUI. But then we'll never know if we have covered enough cases. What are some best practices regarding this?

  • How can I compose a WCF contract out of multiple interfaces?

    - by mafutrct
    I've got multiple interfaces. All of them should be inherited and exposed by a single contract interface. interface A { void X(); } interface B { void Y(); } interface C: A, B {} // this is the public contract How is this possible? I can't add ServiceContract to A and B because that would lead to multiple endpoints. And I don't want to new-override every method in C.

  • How can a client try to reconnect to a server after a first failed try with WCF?

    - by djerry
    Hey guys, I'm using a client - server app. When a client starts, he gets a login-screen. When the server is not up yet, the call to the server will throw an exception which i catch (EndpointNotFoundException). I show a messagebox telling the user the server is offline. When he tries to reconnect again, it will throw another exception (CommunicationObjectFaultedException), even though the server is online. When a new client starts then, he can connect to the server. But the client who attempted before, still gets the error. My question now is how can the first client login after a failed first try without having to start his program again. So i want to clear the communicationchannel of its faulted state or something like that. Thanks in advance.

  • How can I push a string from one client connected to a WCF service to another connected as well?

    - by Sergio Tapia
    Here's what I have so far: IService: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; namespace ServiceLibrary { [ServiceContract(SessionMode = SessionMode.Allowed, CallbackContract = typeof(IServiceCallback))] public interface IService { [OperationContract(IsOneWay = false, IsInitiating = true, IsTerminating = false)] void Join(string userName); } interface IServiceCallback { [OperationContract(IsOneWay = true)] void UserJoined(string senderName); } } Service: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; namespace ServiceLibrary { [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Multiple)] public class Service:IService { IServiceCallback callback = null; public void Join(string userName) { callback = OperationContext.Current.GetCallbackChannel<IServiceCallback>(); } } } Just a simple string passed from one client to another.

  • How do I construct a request for a WCF http post call?

    - by James Hay
    I have a really simple service that I'm messing about with defined by: [OperationContract] [WebInvoke(UriTemplate = "Review/{val}", RequestFormat = WebMessageFormat.Xml, Method = "POST", BodyStyle=WebMessageBodyStyle.Bare)] void SubmitReview(string val, UserReview review); UserReview is, at the moment, a class with no properties. All very basic. When I try and test this in Fiddler I get a bad request status (400) message. I'm trying to call the service using the details: POST http://127.0.0.1:85/Service.svc/Review/hello Headers User-Agent: Fiddler Content-Type: application/xml Host: 127.0.0.1:85 Content-Length: 25 Body <UserReview></UserReview> I would think i'm missing something fairly obvious. Any pointers?

  • How to set the MaxReceivedMessageSize programatically when using a WCF Client?

    - by Pratt
    I want to set the MaxReceivedMessageSize property to some higher limit (Due to (400) Bad Request error) in my client programatically. This is the code I am using... WCFServiceTestClient wcfClient = new WCFServiceTestClient(new wsHttpBinding(), strServiceURL); My service url is dynamic and hence cannot use the web.config. //The following code doesnt seem to take effect ((WSHttpBinding)wcfClient.ChannelFactory.Endpoint.Binding) .MaxReceivedMessageSize = 2147483647; What am I doing wrong? Any help is appreciated. Thanks Pratt

  • How to Transfer Large File from MS Word Add-In (VBA) to Web Server?

    - by Ian Robinson
    Overview I have a Microsoft Word Add-In, written in VBA (Visual Basic for Applications), that compresses a document and all of it's related contents (embedded media) into a zip archive. After creating the zip archive it then turns the file into a byte array and posts it to an ASMX web service. This mostly works. Issues The main issue I have is transferring large files to the web site. I can successfully upload a file that is around 40MB, but not one that is 140MB (timeout/general failure). A secondary issue is that building the byte array in the VBScript Word Add-In can fail by running out of memory on the client machine if the zip archive is too large. Potential Solutions I am considering the following options and am looking for feedback on either option or any other suggestions. Option One Opening a file stream on the client (MS Word VBA) and reading one "chunk" at a time and transmitting to ASMX web service which assembles the "chunks" into a file on the server. This has the benefit of not adding any additional dependencies or components to the application, I would only be modifying existing functionality. (Fewer dependencies is better as this solution should work in a variety of server environments and be relatively easy to set up.) Question: Are there examples of doing this or any recommended techniques (either on the client in VBA or in the web service in C#/VB.NET)? Option Two I understand WCF may provide a solution to the issue of transferring large files by "chunking" or streaming data. However, I am not very familiar with WCF, and am not sure what exactly it is capable of or if I can communicate with a WCF service from VBA. This has the downside of adding another dependency (.NET 3.0). But if using WCF is definitely a better solution I may not mind taking that dependency. Questions: Does WCF reliably support large file transfers of this nature? If so, what does this involve? Any resources or examples? Are you able to call a WCF service from VBA? Any examples?

  • Workflowing an InfoPath form

    - by Donaldinio
    I have an InfoPath form that requires workflow. The form is build from a cXML schema in BizTalk,then dropped into a forms library for workflow. The user opens the infopath form, reviews and picks one of several options: re-submit, archive, escalate, etc. My question is how best to workflow this? Do you have the buttons on the form update a status/action field, and have the workflow listen for an onChange event? Can you update a property on the library, that is not a field on the form? for example, if status is not part of the form schema, but is a column on the document library. How do ye typically do this? thanks.

  • WCF. Robust big file transfer.

    - by Sharov
    Hello everybody! I want to transfer big files (1GB) over unreliable transport channels. When connection is interrupted, I don't want start file transfering from the begining. I can partially store it in a temp table and store last readed position, so when connection is reestablished I can request continue uploading of file from this position. Is there any best-practice for such kind of things. I'm currently use chunking channel. Thanks in advance.

  • Sharing a fabfile across multiple projects

    - by Matthew Rankin
    Fabric has become my deployment tool of choice both for deploying Django projects and for initially configuring Ubuntu slices. However, my current workflow with Fabric isn't very DRY, as I find myself: copying the fabfile.py from one Django project to another and modifying the fabfile.py as needed for each project (e.g., changing the webserver_restart task from Apache to Nginx, configuring the host and SSH port, etc.). One advantage of this workflow is that the fabfile.py becomes part of my Git repository, so between the fabfile.py and the pip requirements.txt, I have a recreateable virtualenv and deployment process. I want to keep this advantage, while becoming more DRY. It seems that I could improve my workflow by: being able to pip install the common tasks defined in the fabfile.py and having a fab_config file containing the host configuration information for each project and overriding any tasks as needed Any recommendations on how to increase the DRYness of my Fabric workflow?

  • WCF dependency on HTTP Filter - what to do with Win 2008 server?

    - by Saar
    We had the same problem described here. we implemented the same solution of having a dependency on HTTPFilter. We recently tried to install on Windows 2008 - it appears the HTTPFilter service is not available there, so our service will not start. What should we do on Windows 2008? Do we need to add a dependency on another service? Which? Thanks Saar

  • Using 50+ 3rd party web services, should I use BizTalk or just C#?

    - by typemismatch
    I'm building a back-end application that needs to fetch data on various schedules from over 50+ 3rd party web services and that number will continue to grow. The data from these services can currently be grouped into 3 types so each response needs to be mapped to 1 of 3 known schemas. Writing custom c# to hit each web service appears to be a management nightmare never mind having all that data mapping in code. The current thinking is build this on top of BizTalk 2009, still a lot of maintenance but at least a well defined platform with mapping/transformation capabilities already. I'm looking for any advise from anyone who might have done this before, does this really buy us anything? I am aware of a lack of polling features in BTS however there are enough work arounds to feel comfortable about the solution. Thanks!

  • Is RIA Services right for our Silverlight app at this point?

    - by Alex
    Hi, I'm looking at Silverlight architectures and RIA Services looks interesting, but I am a bit concerned about its prelease status and how the feature set will change. We need our client app to be as responsive as possible over a slow network link, so a high priority is a solid sync system for pushing model state changes from the client back to the server. Will RIA Services help us in this regard or will I have to roll my own logic to do this ? Are there any other frameworks that can assist with this? Is the feature set involved in these requirements liable to change much in the next couple of months? If it makes any difference, our frontend is 100% Silverlight, so we dont need to worry about exposing SOAP APIs from the server or anything like that. It appears to me that RIA so far is a bit more mature for Silverlight use. Is this correct?

  • How can I avoid huge communication classes in WCF?

    - by mafutrct
    My understanding is that all contract-implementing code has to be in a single class, that can become very large, obviously. How do I avoid this? I really prefer to have a few small classes doing one part of the communication with clients than a single behemoth class. The only idea I could think of is using multiple interfaces implemented by a single class split up by partial, but I don't this this is really solving the issue.

  • Why does my WCF service return and ARRAY instead of a List <T> ?

    - by user193189
    In the web servce I say public List<Customer> GetCustomers() { PR1Entities dc = new PR1Entities(); var q = (from x in dc.Customers select x).ToList(); return q; } (customer is a entity object) Then I generate the proxy when I add the service.. and in the reference.cd it say public wcf1.ServiceReference1.Customer[] GetCustomers() { return base.Channel.GetCustomers(); } WHY IS IT AN ARRAY? I asked for a List. help.
