  • Question about using ServiceModelEx's "WCFLogbook" from "Programming WCF Services" book

    - by Bill
    I am attempting to compile/run a sample WCF application from Juval Lowy's website (author of Programming WCF Services & founder of IDesign). Of course the example application utilizes Juval's ServiceModelEx library and logs faults/errors to a "WCFLogbook" database. Unfortunately, when the sample app faults, I get the following new error: "Cannot open database "WCFLogbook" requested by the login. The login failed. Login failed for user 'Bill-PC\Bill'." I suspect the error occurs as a result of not finding the "WCFLogbook" database, which I believe still needs to be created. Included in the library source directory, there are two files -WCFLogbookDataSet.xsd and WCFLogbook.sql; which neither seem to be referenced anywhere within the library code. This leads me to beleive that the sql and xsd files are there to be used to create the database somehow in SQL. Could someone please advise me if I am going in the correct direction here and if whether these files can be used to create the database (and if so, how)?

  • WCF fault logging and SQL Exception 4060 error.

    - by Bill
    I have been attempting to compile/run a sample WCF application from Juval Lowy's website (author of Programming WCF Services & founder of IDesign) for several days. The example app utilizes Juval's ServiceModelEx library which logs faults/errors to a "WCFLogbook" SQL database. Unfortunately, when the sample app faults, I get the following error: SQL Exception 4060: "Cannot open database \"WCFLogbook\" requested by the login. The login failed.\r\nLogin failed for user 'Bill-PC\Bill'." I confirmed that the SQL WCFLogbook database has been created and have granted all of the appropriate permissions for my (Bill-PC\Bill) access to the database. Additionally port 8006 and port 1433 have been opened in the Firewall. TCP/IP has been enabled and "Allow remote connections to this server" has been checked. I am using the following endpoint within the App.Config file: <client> <endpoint name="LogbookTCP" address="net.tcp://Bill-PC:8006/LogbookManager" binding="netTcpBinding" contract="ILogbookManager" /> </client> Unfortunately SQL is a 'world' that I hadn't needed to venture into before now and I am terribly frustrated with my lack of success. Would anyone have any other suggestions on how to get this working? Have I missed anything?

  • Limiting calls to WCF services from BizTalk

    - by IntegrationOverload
    ** WORK IN PROGRESS ** This is just a placeholder for the full article that is in progress. The problem My BTS solution was receiving thousands of messages at once. After processing by BTS I needed to send them on via one of several WCF services depending on the message content. The problem is that due to the asynchronous nature of BizTalk the WCF services were getting hammered and could not cope with the load. Note: It is possible to limit the SOAP calls in the BtsNtSvc.exe.Config file but that does not have the desired results for Net-TCP WCF services. The solution So I created a new MessageType for the messages in question and posted them to the BTS messaeg box. This schema included the URL they were being sent to as a promoted property. I then subscribed to the message type from a new orchestraton (that does just the WCF send) using the URL as a correlation ID. This created a singleton orchestraton that was instantiated when the first message hit the message box. It then waits for further messages with the same correlation ID and type and processs them one at a time using a loop shape with a timer (A pretty standard pattern for processing related messages) Image to go here This limits the number of calls to the individual WCF services to 1. Which is a good start but the service can handle more than that and I didn't want to create a bottleneck. So I then constructed the Correlation ID using the URL concatinated with a random number between 1 and 10. This makes 10 possible correlation IDs per URL and so 10 instances of the singleton Orchestration per WCF service. Just what I needed and the upper random number is a configuration value in SSO so I can change the maximum connections without touching the code.

  • Does GoDaddy supports RESTful services via WCF

    - by Amir Naor
    After deploying a WCF RESTful service that i created using the REST started kit, i got several errors that i managed to solve following this post: http://www.edoverip.com/edoverip/index.php/2009/01/30/running-wcf-on-godaddy Now i'm stuck with this error: IIS specified authentication schemes 'Basic, Anonymous', but the binding only supports specification of exactly one authentication scheme. Valid authentication schemes are Digest, Negotiate, NTLM, Basic, or Anonymous. Change the IIS settings so that only a single authentication scheme is used I saw that others got to this point without a solution. GoDaddy support dont know nothing. Is it possible at all? Are there any web hosting services that you know that support that?

  • Consume WCF Web Service in Objective-C on an iPhone

    - by JWD
    I am having a hard time consuming a very simple (Hello World) WCF web service in my iPhone app. From what I have read, you must manually create the request message then send it to the web service URL. I was able to accomplish this on a .asmx web service, but not with a WCF service. How do I know the correct format of the request SOAP message? The web service I am trying to hit has a format of: http://xxx.xxx.xxx.xxx:PORT/IService1/ (running locally in a VM) I apologize for the lack of information, I am pretty lost. Any and all help is much appreciated. Thanks in advance!

  • Delphi SOAP Envelope and WCF

    - by Chris
    Hi all, I am working on a system that provides a soap interface. One of the systems that are going to use the interface is coded in Delphi 7. The web service is developed with WCF, basic http binding, SOAP 1.1. If I use SOAP UI (JAVA), the service works properly. But Delphi seems to do special things here ;) This is how the message looks like in SOAP UI: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services.xxx.de/xxx"> <soapenv:Header/> <soapenv:Body> <ser:GetCustomer> <!--Optional:--> <ser:GetCustomerRequest> <!-- this is a data contract --> <ser:Id>?</ser:Id> </ser:GetCustomerRequest> </ser:GetCustomer> </soapenv:Body> </soapenv:Envelope> I am not a delphi developer , but I developed a simple test client to see what's going wrong. This what Delphi sends as a SOAP envelope. <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Body SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:NS2="http://services.xxx.de/xxx"> <NS1:GetCustomer xmlns:NS1="http://services.xxx.de/xxx"> <GetCustomerRequest href="#1"/> </NS1:GetCustomer> <NS2:GetCustomerRequest id="1" xsi:type="NS2:GetCustomerRequest"> <Id xsi:type="xsd:int">253</Id> </NS2:GetCustomerRequest> </SOAP-ENV:Body> </SOAP-ENV:Envelope> WCF throws an error that is in German language... ;) Es wurde das Endelement "Body" aus Namespace "http://schemas.xmlsoap.org/soap/envelope/" erwartet. Gefunden wurde "Element "NS2:GetCustomerRequest" aus Namespace "http://services.xxx.de/xxx"". Zeile 1, Position 599. Means something like The Body was expected. But instead the Element "NS2:GetCustomerReques" was found. Now my questions is: Can I somehow change the way Delphi creates the envelope? Or are the ways to make WCF work with such message formats? Any help is greatly appreciated!

  • Interesting issue with WCF wsHttpBinding through a Firewall

    - by Marko
    I have a web application deployed in an internet hosting provider. This web application consumes a WCF Service deployed at an IIS server located at my company’s application server, in order to have data access to the company’s database, the network guys allowed me to expose this WCF service through a firewall for security reasons. A diagram would look like this. [Hosted page] --- (Internet) --- |Firewall <Public IP>:<Port-X >| --- [IIS with WCF Service <Comp. Network Ip>:<Port-Y>] link text I also wanted to use wsHttpBinding to take advantage of its security features, and encrypt sensible information. After trying it out I get the following error: Exception Details: System.ServiceModel.EndpointNotFoundException: The message with To 'http://<IP>:<Port>/service/WCFService.svc' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree. Doing some research I found out that wsHttpBinding uses WS-Addressing standards, and reading about this standard I learned that the SOAP header is enhanced to include tags like ‘MessageID’, ‘ReplyTo’, ‘Action’ and ‘To’. So I’m guessing that, because the client application endpoint specifies the Firewall IP address and Port, and the service replies with its internal network address which is different from the Firewall’s IP, then WS-Addressing fires the above message. Which I think it’s a very good security measure, but it’s not quite useful in my scenario. Quoting the WS-Addressing standard submission (http://www.w3.org/Submission/ws-addressing/) "Due to the range of network technologies currently in wide-spread use (e.g., NAT, DHCP, firewalls), many deployments cannot assign a meaningful global URI to a given endpoint. To allow these ‘anonymous’ endpoints to initiate message exchange patterns and receive replies, WS-Addressing defines the following well-known URI for use by endpoints that cannot have a stable, resolvable URI. http://schemas.xmlsoap.org/ws/2004/08/addressing/role/anonymous" HOW can I configure my wsHttpBinding Endpoint to address my Firewall’s IP and to ignore or bypass the address specified in the ‘To’ WS-Addressing tag in the SOAP message header? Or do I have to change something in my service endpoint configuration? Help and guidance will be much appreciated. Marko. P.S.: While I find any solution to this, I’m using basicHttpBinding with absolutely no problem of course.

  • WCF DataContract with readonly properties

    - by Asaf R
    Hi, I'm trying to return a complex type from a service method in WCF. I'm using C# and .NET 4. This complex type is meant to be invariant (the same way .net strings are). If I try to define only getters on properties I get a run time error. I guess this is because no setters causes serialization to fail. Still, I think this type should be invariant. Is there a way to make readonly properties on a WCF DataContract? Is, how? If not, what would you suggest for this problem? Thanks, Asaf

  • .net WCF DateTime

    - by freddy smith
    I want to be able to safely send DateTime's over WCF without having to worry about any implicit or automatic TimeZone conversions. The dates I want to send are "logical" dates. year month day, there should be no time component. I have various server processes and client process that run on a variety of machines with different TimeZone settings. What I would like to ensure is that when a user enters a date in a textfield (or uses a date picker component) on any client that exact what they see at data entry is what is sent over WCF, used by the server and seen by other clients when they request the data. I am a little confused by the various questions and answers on this site concerning DateTime.Kind (unspecified, UTC, local).

  • WCF Data Services consuming data from EF based repository

    - by John Kattenhorn
    We have an existing repository which is based on EF4 / POCO and is working well. We want to add a service layer using WCF Data Services and looking for some best practice advice. So far we have developed a class which has a IQueryable property and the getter triggers the repository 'get all users' method. The problem so far have been two-fold: 1) It required us to decorate the ID field of the poco object to tell data service what field was the id. This now means that our POCO object is not 'pure'. 2) It cannot figure out the relationships between the objects (which is obvious i guess). I've now stopped this approach and i'm thinking that maybe we should expose the OBjectContext from the repository and use more 'automatic' functionality of EF. Has anybody got any advice or examples of using the repository pattern with WCF Data Services ?

  • Session variable in WCF application

    - by kaivalya
    I need to use or stimulate a very simple session object inside my WCF app. I simply need to store some values at the beginning of a call and I need access to these values while I go through some different methods of my service. Asp.NET session would be very ideal to use for this so I need to find out what is available on a WCF app for storing such values. Note: this is just a per call session, I don't need to retain this session between different calls from the client to service and such..

  • How can I add a prefix to a WCF ServiceContract Namespace

    - by Lodewijk
    Hi, I'm trying to implement an UPnP MediaServer in WCF. I'm slowly getting there, but now I've hit a brick wall. I need to add a prefix to the ServiceContract namespace. Right now I have the following: [ServiceContract(Namespace = "urn:schemas-upnp-org:service:ContentDirectory:1")] public interface IContentDirectory { [OperationContract(Action = "urn:schemas-upnp-org:service:ContentDirectory:1#Browse")] void Browse(string ObjectID, string BrowseFlag, string Filter, ulong StartingIndex, ulong RequestedCount, string SortCriteria, out string Result, out ulong NumberReturned, out ulong TotalMatches, out ulong UpdateID); } This listens to the correct soap-messages. However, I need the soap-body to begin with <u:Browse xmlns-u="urn:schemas-upnp-org:service:ContentDirectory:1"> and WCF is now listening to: <Browse xmlns="urn:schemas-upnp-org:service:ContentDirectory:1"> How do I get the prefix there? Does it matter? Or is there another reason why the parameters are not passed into the Browse method?

  • WCF RIA Services build error

    - by soren.enemaerke
    Hi I'm getting a strange error when building my WCF RIA Services Silverlight project in VS2008. In the output I have this message: C:\Program Files\MSBuild\Microsoft\Silverlight\v3.0\Microsoft.Ria.Client.targets(261,5): error : Failed to write the generated contents of 'C:\projects\[Path_To_Silverlight_Project]\Generated_Code\Analytics.Web.g.cs' to Visual Studio. ...and Visual Studio opens a dialog while building with the following: An editor or project is attempting to save a file that is modified in memory. Saving files during a build is dangerous and may result in incorrect build outputs in the future. Continue with save? The other members on my team seems to be doing just fine, but I can't get past this point (I can if I click 'Continue' which then generate the file just fine but I'm reluclant to do so). There must be some setup or similar that I'm missing here... PS: I'm currently on WinXP and WCF RIA Service beta

  • TimeoutException in simultaneous calls to WCF services from Silverlight application

    - by Alexander K.
    Analysing log files I've noticed that ~1% of service calls ended with TimeoutException on the Silverlight client side. The services (wcf) are quite simple and do not perform long computations. According the log all calls to the services are always processed in less that 1 sec (even when TimeoutException is occurred on the client!), so it is not server timeout. So what is wrong? Can it be configuration or network problem? How can I avoid it? What additional logging information can be helpful for localizing this issue? The only one workaround I've thought up is to retry service calls after timeout. I will appreciate any help on this issue! Update: On startup the application performs 17 service calls and 12 of them simultaneously (may it be cause of failure?). Update: WCF log has not contained useful information about this issue. It seems some service calls do not reach the server side.

  • Entity Framework and consuming a WCF service

    - by nakori
    I'm getting data where the database is hidden behind a WCF service. Is it possible to use Entity Framework in a scenario where I have custom objects coming from a web service? (No access to the external database, and no current plans for insert/update/delete logic) Starting with an empty EF model and adding an entity I get this error on compile: No mapping specified for instances of the EntitySet and AssociationSet in the EntityContainer .. Is it possible to make an entity this way, and fill it with data received from an object? (In this case a WCF, but could also be a predefined model class/xml data) If the web service retured a Customer object I could do something like this with a dataset: Make an unbound table and do a loop through the customer properties adding them to a temp row, add it with tbl_Customer.Addtbl_CustomerRow(customerRow) to get my view filled. thanks, nakori

  • Config for WCF with multiple endpoints

    - by vdh_ant
    Hi guys I'm new to WCF and am trying to get some ideas I have off the ground. Basically I have a web WCF Application project with the following in its web.config: <system.serviceModel> <services> <service name="WcfService1.ServiceContract.IDirectorySearchService" behaviorConfiguration="defaultServiceBehavior"> <endpoint name="restxml" address="xml" binding="webHttpBinding" contract="WcfService1.ServiceContract.IDirectorySearchServiceXml" behaviorConfiguration="xmlRestBehavior"/> <endpoint name="restjson" address="json" binding="webHttpBinding" contract="WcfService1.ServiceContract.IDirectorySearchServiceJson" behaviorConfiguration="jsonRestBehavior"/> <endpoint name="soap" address="soap" binding="basicHttpBinding" contract="WcfService1.ServiceContract.IDirectorySearchService"/> <endpoint name="mex" address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="defaultServiceBehavior"> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="xmlRestBehavior"> <webHttp/> </behavior> <behavior name="jsonRestBehavior"> <enableWebScript/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> My interfaces look like this: [ServiceContract] public interface IDirectorySearchServiceXml { [OperationContract] [WebGet(UriTemplate = "Search/")] SearchResults Search(); } [ServiceContract] public interface IDirectorySearchServiceJson { [OperationContract] [WebGet(UriTemplate = "Search/")] SearchResults Search(); } [ServiceContract] public interface IDirectorySearchService { [OperationContract] SearchResults Search(int? sportId, int? instituteId, DateTime? startDate, DateTime? endDate); } Now the part I am having a little trouble with is what else I need to get this up and running... Like given this what .svc files do I need and do I have the config right... Also what addresses do I need to use to get this running either through the browser or through the WCF test client. Note I am currently using 3.5. Cheers Anthony

  • Win CE 6.0 client using WCF Services

    - by Sean
    We have a Win CE 6.0 device that is required to consume services that will be provided using WCF. We are attempting to reduce bandwidth usage as much as possible and with a simple test we have found that using UDP instead of HTTP saved significant data usage. I understand there are limitations regarding WCF on .NET Compact Framework 3.5 devices and was curious what people thought would be the appropriate way forward. Would it make sense to develop a custom UDP binding, and would that work for both sides? Any feedback would be appreciated. Thanks.

  • WCF performance improvements

    - by Burt
    I am developing a WPF application that talks to a server via WCF services over the internet. After profiling the application I noticed a lot of time is being taking up by creating the appropriate WCF client proxy and making the call to the server. The code on the server is optimised and doesn't take any time to run yet I am still seeing a 1.5 second delay from when a service is invloked to it returning to the client. A few points to give a bit of background: I am using the ASP.Net membership for security I will eventually hook into the same server side code through a website I would eventually like to have offline support in the application I really need to nail the performance early though as if the app is taking a couple of seconds to come back it is too long for what I am trying to do. Can anyone suggest performance tips that will help me please?

  • HTTP 404 Error manifests itself as EndPointNotFoundException on a WCF client

    - by dudia
    How can I make my client treat 404 Error correctly? Right now it catches a general exception... My WCF Server uses WebOperationContext.Current.OutgoingResponse.SetStatusAsNotFound(); To return a 404 Error code however my WCF client interperts it as an EndPointNotFoundException There was no endpoint listening at http://myUrl that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. The inner exception is WebException "The remote server returned an error: (404) Not Found.

  • IIS7 + WCF + Silverlight problems

    - by Eanna
    Hey, I've been building a silverlight application and a WCF service for a while now and recently tried to host them in IIS7. I installed IIS7 on Windows Server 2008 R2 and added these two application to my default website. I am having a number of problems so im hoping one of you can help out... 1) The silverlight and WCF service applications do not work with pass-through authentication. I need to "connect as" the administrator server account when setting up the application. I read online that you should only need to use the "connect as" field when you are connecting to another computer. If i dont supply the admin credentials i get this error. Do i have to set up permissions somewhere else? HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Detailed Error Information Module IIS Web Core Notification BeginRequest Handler Not yet determined Error Code 0x80070005 Config Error Cannot read configuration file due to insufficient permissions Config File \?\C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\WCFService\Website\web.config Requested URL http:://localhost:80/WCFService/Service.svc Physical Path C:\Users\Administrator\Documents\My Dropbox\Research Masters\Project\WCFService\Website\Service.svc Logon Method Not yet determined Logon User Not yet determined Config Source -1: 0: Links and More Information This error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error. 2) Visual studio generated 2 webpages to run my silverlight application (.html and .aspx). When I am running the silverlight application (connected as admin) I can navigate to the .html page, no problem. When I try to open the .aspx file i get the following error Server Error in '/Platform' Application. Access is denied. Description: An error occurred while accessing the resources required to serve this request. You might not have permission to view the requested resources. Error message 401.3: You do not have permission to view this directory or page using the credentials you supplied (access denied due to Access Control Lists).

Version Information: Microsoft .NET Framework Version:4.0.30128; ASP.NET Version:4.0.30128.1 3) The WCF service runs fine (again, connected as admin) until i restart the server.

  • Only send populated object properties over WCF?

    - by dlanod
    I have an object that is being sent across WCF that is essentially a property holder - it can potentially have a large number of properties, i.e. up to 100, but in general only a small subset will be set, up to 10 for instance. Example: [DataContract(Namespace = "...")] public class Monkey { [DataMember] public string Arms { get; set; } [DataMember] public string Legs { get; set; } [DataMember] public string Heads { get; set; } [DataMember] public string Feet { get; set; } [DataMember] public string Bodies { get; set; } /* repeat another X times */ } Is there a way to tell WCF to only send the populated properties over the wire? It seems like a potential waste of bandwidth to send over the full object.

  • WCF MessageContract Help - MessageBodyMember with hyphenated name

    - by Hcabnettek
    Hi All, I need a bit of WCF help. This project uses message contracts. The transport seems to work ok. I have this code for a response type. namespace tpoke.Contracts { [MessageContract(IsWrapped = true)] public class AuthenticationResponseMC { [MessageBodyMember(Name = "authentication-token")] public Guid AuthenticationToken; } } Now when I run the operation that returns this, I try to deserialize using the XmlSerializer. The is not what I'm needing. I need it to be <authentication-token xmlns="http://tpoke.wcf.com">e13xxxx-xxxx-xxxx-xxxxxx</authentication-token> How can I make this work correctly? Do I need to add the namespace to MessageBodyMember? Why is the hyphen being stripped out? Any tips or advice is certainly appreciated. Thanks, ~ck in San Diego

  • ASP.NET / WCF - Execute Server.Execute Asynchronously

    - by user208662
    Hello, I need to run the HttpContext.Current.Server.Execute method in my ASP.NET application. This application has a WCF operation that does some processing. Currently, I am to do my processing correctly from within my WCF operation. However, I would like to do this asynchronously. In an error to attempt this asynchronously, I tried running Server.Execute in the DoWork event handler of a BackgroundWorker. Unfortunately, this throws an error that says "object reference not set to an instance of an object" The HttpContext element is not null. I checked that. It is some property nested in the HttpContext object that appears to be null. However, I have not been able to identify why this won't work. It happens as soon as I move the processing to the BackgroundWorker thread. My question is, how can I asynchronously execute the Server.Execute method? Thank you,
