  • NHibernate & WCF in version 3.0

    - by ChrisKolenko
    Hi everyone :D I've just started a new project which requires a WCF service to handle a distributed environment. I'm still trying to find the best way to implement things. I want to use NHibernate, but I've seen a few different ways to address the serialization. Is this handled in 3.0? I noticed wcf_context inside the truck :D If it isn't handled could someone point me in the right direction? Thanks everyone

  • WCF: 'Update Service Reference' hoses my files.

    - by mcoolbeth
    Every time that I make a change to the contract of my WCF service, I need to have Visual Studio update the service references in all of my client projects. This process regenerates my client's app.config file and, since I have hand-tuned the "bindings" section of the file, I need to back-up my file and then restore it each time I have VS do the update. Is there a way to avoid this necessity (eg: have VS update the service reference without rewriting anything in app.config)? Thanks

  • Hosting a WCF Service Lib through a Windows service get a System.InvalidOperationException: attempti

    - by JohnL
    I have a WCF Service Library containing five service contracts. The library is hosted through a Windows Service. Most if not all my configuration for the WCF Library is declaritive. The only thing I am doing in code for configuration is to pass the type of the class implementing the service contracts into ServiceHost. I then call Open on each of the services during the Windows Service OnStart event. Here is the error message I get: Service cannot be started. System.InvalidOperationException: Service '[Fubu.Conversion.Service1' has zero application (non-infrastructure) endpoints. This might be because no configuration file was found for your application, or because no service element matching the service name could be found in the configuration file, or because no endpoints were defined in the service element. at System.ServiceModel.Description.DispatcherBuilder.EnsureThereAreNonMexEndpoints(ServiceDescription description) at System.ServiceModel.Description.DispatcherBuilder.InitializeServiceHost(ServiceDescription description, ServiceHostBase serviceHost) at System.ServiceModel.ServiceHostBase.InitializeRuntime() at System.ServiceModel.ServiceHostBase.OnBeginOpen() at System.ServiceModel.ServiceHostBase.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open() at Fubu.RemotingHost.RemotingHost.StartServ... protected override void OnStart(string[] args) { // Uncomment to debug this properly //System.Diagnostics.Debugger.Break(); StartService1(); StartService2(); StartService3(); StartService4(); StartService5(); } Each of the above simply do the following: private void StartSecurityService() { host = new ServiceHost(typeof(Service1)); host.Open(); } Service Lib app.congfig summary <services> <service behaviorConfiguration="DefaultServiceBehavior" name="Fubu.Conversion.Service1"> <endpoint address="" binding="netTcpBinding" bindingConfiguration="TCPBindingConfig" name="Service1" bindingName="TCPEndPoint" contract="Fubu.Conversion.IService1"> <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" name="mexSecurity" bindingName="TcpMetaData" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:8025/Fubu/Conversion/Service1/" /> </baseAddresses> </host> </service> ... Contract is set up as follows: namespace Fubu.Conversion.Service1 { [ServiceContract(Namespace = "net.tcp://localhost:8025/Fubu")] public interface IService1 { I have looked "high and low" for a solution without any luck. Is the answer obvious? The solution to this does not appear to be. Thanks

  • Using a WCF Service Library from Silverlight

    - by Ian Oakes
    I've added a WCF Service Library to a Silverlight project. But when I try calling a method on the service I get a CommunicationException complaining about accessing a service in a cross-domain way. I've tried adding both a crossdomain.xml and clientaccesspolicyfile.xml to the service library project, but it doesn't help. Any idea what I'm doing wrong?

  • WCF doesn't find client configuration

    - by ultraman69
    Hi ! I have a WCF service on server B. Then on the machine A is the client, which is a Windows service. In a separate dll stands all the business logic for this service. So my proxy for the WCF is on that side. I have 2 app.config (client side only) : 1 for the service and another one in the dll. So I tried (for test purpose) puting the servicemodel config section in both. Both still, it doesn't work, it says that it can't find the endpoint with that name and for that contract... What I'm trying to do here is modify the configuration programatically. Here' the code in the business layer dll : Dim ep As New EndpointAddress(New Uri(ConfigurationManager.AppSettings(nomServeurCible)), _ EndpointIdentity.CreateDnsIdentity(ConfigurationManager.AppSettings("Identity_" & nomServeurCible))) serviceCible = New ServiceProxy.ExecOperClient("wsHttp", ep) And here is a sample of the config file : <add key="TEST1" value="http://TEST1:8000/MySpacePerso/ExecOperService"/> <add key="TEST1_CertificateSerialNumber" value="10 hj 6y 7b 00 01 32 12 01 21"/> <add key="Identity_TEST1" value="TEST1"/> <system.serviceModel> <client> <endpoint address="http://SERV_NAME:8000/CSSTQDA/ExecOperService" binding="wsHttpBinding" behaviorConfiguration="myClientBehavior" bindingConfiguration="MybindingCon" contract="ExecOper.Service.IExecOper" name="wsHttp"> <identity> <dns value="SERV_CERT_NAME"/> </identity> </endpoint> </client> <bindings> <wsHttpBinding> <binding name="MybindingCon"> <security mode="Message"> <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceTraitementBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="myClientBehavior"> <clientCredentials> <serviceCertificate> <authentication certificateValidationMode="ChainTrust" revocationMode="NoCheck"/> </serviceCertificate> </clientCredentials> </behavior> </endpointBehaviors> </behaviors>

  • Hidden WCF endpoints

    - by Matt
    For the sake of arguement, lets say that I've got a basicHttp WCF service. Besides implementing authentication (login/logout methods), what is stopping someone from just cracking open Visual Studio, adding a web reference to my website's service, and then playing playing around with my service? I'm not familiar with a method of stopping someone from doing this. The idea of someone downloading all of my Data/Operation contracts and then start playing around is keeping me up at night, and I like my sleep!

  • How can I swap WCF deserializer from configuration

    - by JohnIdol
    I have a problem with WCF deserialization where the client hangs on the response for more than a minute. I'd like to try to swap different deserializers and see if it affects the behavior. Can I swap in/out DataContract/Xml serializers (are there any others?) from configuration, and if so can I do that with any binding, or is that out of control once the service reference is imported? Any help appreciated!

  • Sending part of byte array over the network using WCF

    - by nikola
    I have a byte array of some binary data that i need to send over the network using WCF and NetTcpBinding. My problem is that i need to send only the part of the array. Is there any way to do this, other than copying that part to a separate array, and sending that one. This extra copying degrades performance, and i would like to avoid it, if possible.

  • WCF .Net 4.0 is treating WebProtocolException as an unhandled exception

    - by Benjii
    Im trying to build an API using WCF and .Net 4, however when I throw the WebProtocolException, it is not displaying a nice error message like it should, instead it is treating it like an unhandled exception. I am using the WebServiceHost2Factory. Has anyone else used WebProtocolException with .net 4? An example of my call is below throw new WebProtocolException(System.Net.HttpStatusCode.BadRequest, "The DateFrom parameter is invalid", new Error() { Code = 6002, Message = "Please ensure your dates are in the following format: yyyy/MM/dd hh:mm:ss" }, null, null);

  • Access Request Body in a WCF RESTful Service

    - by urini
    Hi, How do I access the HTTP POST request body in a WCF REST service? Here is the service definition: [ServiceContract] public interface ITestService { [OperationContract] [WebInvoke(Method = "POST", UriTemplate = "EntryPoint")] MyData GetData(); } Here is the implementation: public MyData GetData() { return new MyData(); } I though of using the following code to access the HTTP request: IncomingWebRequestContext context = WebOperationContext.Current.IncomingRequest; But the IncomingWebRequestContext only gives access to the headers, not the body. Thanks.

  • Friend WCF Web Service Reference

    - by Bram
    Is it possible to make a WCF reference in a Silverlight DLL private? The option is greyed out and when you edit the Reference.vb file manaully, when running, it complains about not being able to serialize because it is not public. I don't want the service to be exposed outside of the DLL. Is this possible?
