  • WCF ChannelFactory caching

    - by Myles J
    I've just read this great article on WCF ChannelFactory caching by Wenlong Dong. My question is simply how can you actually prove that the ChannelFactory is in fact being cached between calls? I've followed the rules regarding the ClientBase’s constructors. We are using the following overloaded constructor on our object that inherits from ClientBase: ClientBase(string endpointConfigurationName, EndpointAddress remoteAddress); In the article mentioned above it is stated that: For these constructors, all arguments (including default ones) are in the following list: · InstanceContext callbackInstance · string endpointConfigurationName · EndpointAddress remoteAddress As long as these three arguments are the same when ClientBase is constructed, we can safely assume that the same ChannelFactory can be used. Fortunately, String and EndpointAddress types are immutable, i.e., we can make simple comparison to determine whether two arguments are the same. For InstanceContext, we can use Object reference comparison. The type EndpointTrait is thus used as the key of the MRU cache. To test the ChannelFactory cache theory we are checking the Hashcode in the ClientBase constructor e.g. var testHash = RuntimeHelpers.GetHashCode(base.ChannelFactory); The hash value is different between calls which makes us think that the ChannelFactory isn't actually cached. Any thoughts? Regards Myles

  • WCF Restful services getting error 400 (bad request) when post xml data

    - by Wayne Lo
    I am trying to self host a WCF services and calling the services via javascript. It works when I pass the request data via Json but not xml (400 bad request). Please help. Contract: public interface iSelfHostServices { [OperationContract] [WebInvoke(Method = "POST", UriTemplate = INFOMATO.RestTemplate.hello_post2,RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle.Wrapped)] Stream hello_post2(string helloString); } Server side code: public Stream hello_post2(string helloString) { if (helloString == null) { WebOperationContext.Current.OutgoingResponse.StatusCode = System.Net.HttpStatusCode.BadRequest; return null; } WebOperationContext.Current.OutgoingResponse.StatusCode = System.Net.HttpStatusCode.OK; return new MemoryStream(Encoding.UTF8.GetBytes(helloString)); } JavaScript: function testSelfHost_WCFService_post_Parameter() { var xmlString = "<helloString>'hello via Post'</helloString>"; Ajax_sendData("hello/post2", xmlString); } function Ajax_sendData(url, data) { var request = false; request = getHTTPObject(); if (request) { request.onreadystatechange = function() { parseResponse(request); }; request.open("post", url, true); request.setRequestHeader("Content-Type", "text/xml; charset=utf-8"); charset=utf-8"); request.send(data); return true; } } function getHTTPObject() { var xhr = false; if (window.XMLHttpRequest) { xhr = new XMLHttpRequest(); } else if (window.ActiveXObject) {...} }

  • Calling WCF service with parameter using jQuery

    - by Remi Despres-Smyth
    I'm trying to call a WCF web service hosted by IIS using jQuery. I can call it fine without any parameters, and I can also call it fine with a GET request that includes my parameter, but as soon as I try to send in the request via POST, the call is failing. The web service is currently nothing but: [OperationContract, WebInvoke] public ValidationResultSummary TestValidateOn( object day) { return null; } I've set the parameter to object, to make sure the issue isn't something with type coercion. With a breakpoint in the web service, I know the call without parameters as well as the GET call with param succeeds; in the latter the expected value is sent up. Calling code looks like: $.ajax({ // type: "GET", // url: "../Shared/Services/DomainServices.svc/TestValidateOn?day='12/Jan/2010'", type: "POST", url: "../Shared/Services/DomainServices.svc/TestValidateOn", // data: "{ }", --This works if object type param, calls with null data: "{'day': " + selectedDate + "}", // This fails miserably // data: "{'day': '" + selectedDate + "'}", --This also fails miserably contentType: "application/json; charset=utf-8", dataType: "json", success: function(data) { displayResults(data.d); }, error: function(xmlHttpReq, status, errThrown) { displayError(xmlHttpReq, status, errThrown); } }); The POST call never reaches my breakpoint, and on the client, error 500 - "Internal Server Error" - is returned. Any help would be appreciated.

  • Unable to debug WCF service in VS2008 after UserNamePasswordValidator fault

    - by lsb
    Hi! I have a WCF service that I secure with a custom UserNamePasswordValidator and Message security running over wsHttpBinding. The release code works great. Unfortunately, when I try to run in debug mode after having previously used invalid credentials (the current credentials ARE valid!) VS2008 displays an annoying dialog box (more on this below). A simplified version of my Validate method from the validator might look like the following: public override void Validate(string userName, string password) { if (password != "ABC123") throw new FaultException("The password is invalid!"); } The client receives a MessageSecurityException with InnerException set to the FaultException I explictly threw. This is workable since my client can display the message text of the original FaultException I wanted the user to see. Unfortunately, in all subsequent service calls VS2008 displays an "Unable to automatically debug..." dialog. The only way I can stop this from happening is to exit VS2008, get back in and connect to my service using correct credentials. I should also add that this occurs even when I create a brand new proxy on each and every call. There's no chance MY channel is faulted when I make a call. Its likely, however, that VS2008 hangs on to the previously faulted channel and tries to use it for debugging purposes. Needless to say, this sucks! The entire reason I'm entering "bad" credentials is to test the "bad-credential" handling. Anyway, if anyone has any ideas as to how I can get around this bug (?!?) I'd be very very appreciative....

  • Dynamics CRM 2011 - WCF error

    - by bigtv
    I am trying to get to grips with MS Dynamics CRM 2011. I have have the beta installed on a VM and things look pretty good - some great new features etc. However I am getting an exception when trying to connect to the new XRMServices (updated 2011 WCF web services) Exception: System.ServiceModel.ServiceActivationException: The service '/organame/XRMServices/2011/Organization.svc' cannot be activated due to an exception during compilation. The exception message is: 'System.ServiceModel.Description.UseRequestHeadersForMetadataAddressBehavior'. This collection only supports one instance of each type. Parameter name: item. ---> System.ArgumentException: The value could not be added to the collection, as the collection already contains an item of the same type: 'System.ServiceModel.Description.UseRequestHeadersForMetadataAddressBehavior'. This collection only supports one instance of each type. Parameter name: item The only reference to this exception I gave found suggests that it is caused by multiple bindings configured in IIS, which in my case I did have, but the problem persists even after removing them. Any suggestions would be appreciated.

  • Self hosted WCF ServiceHost/WebServiceHost Concurrency/Peformance Design Options (.NET 3.5)

    - by Kyle
    So I'll be providing a few functions via a self hosted (in a WindowsService) WebServiceHost (not sure how to process HTTP GET/POST with ServiceHost), one of which may be called a large amount of the time. This function will also rely on a connection in the appdomain (hosted by the WindowsService so it can stay alive over multiple requests). I have the following concerns and would be oh so thankful for any input/thoughts/comments: Concurrent access - how does the WebServiceHost handle a bunch of concurrent requests. Are they queued and processes sequentially or are new instances of the contracts automagically created? WebServiceHost - WindowsService communication - I need some form of communication from the WebServiceHost to the hosting WindowsService for things like requesting a new session if one does not exist. Perhaps implementing a class which extends the WebServiceHost with events which the WindowsService subscribes to... (unless there is another way I can set off an event in the WindowsService when a request is made...) Multiple WebServiceHosts or Contracts - Would it give any real performance gain to be running multiple WebServiceHost instances in different threads (one per endpoint perhaps?) - A better understanding of the first point would probably help here. WSDL - I'm not sure why (probably just need to do more reading), but I'm not sure how to get the WebServiceHost base endpoint to respond with a WDSL document describing the available contract. Not required as all the operations will be done via GET requests which will not likely change, but it would be nice to have... That's about it for the moment ;) I've been reading a lot on WCF and wish I'd gotten into it long ago, but definitely still learning.

  • Understanding ServiceKnownType in WCF

    - by SLC
    I am having a little trouble understanding ServiceKnownType in WCF. Taken from this blog, the following code does not work: [DataContract(Namespace = “http://mycompany.com/”)] public class Shape{…} [DataContract(Namespace = “http://mycompany.com/”)] public class Circle : Shape {…} [ServiceContract] public interface IMyServer { [OperationContract] bool AddShape(Shape shape); } . IMyServer client = new ChannelFactory<IMyServer>(binding, endPoint).CreateChannel(); client.AddShape(new Circle()); The reason it doesn't work is because you are trying to add a circle, but the servicecontract only allows a Shape. You are supposed to do something with knowntypes, but I am a bit confused about how that works. Since that code is in the service, why doesn't it know automatically that a Circle is derived from Shape? Additionally, what does ServiceKnownType actually do? When ServiceKnownType is put below the DataContract, apparently that makes it work. I am guessing it says hey, this particular object type called Shape can also be a Circle. I am having trouble understanding why it would do it this way around, because if you add a new type like Square you are going to have to add that too, wouldn't it make sense if it cannot infer it, to put the KnownType onto the Square rather than the Shape? So the Square says hey, I am a Shape, and you don't have to fiddle with the Shape class?

  • Multiple Base Addresses and Multiple Endpoints in WCF

    - by mnhab
    I'm using two bindings TCP and HTTP. I want to give mex data on both bindings. What I want is that the mexHttpBinding only exposes the HTTP services while the mexTcpBinding exposes TCP services only. Or is this possible that I access stats service only from HTTP binding and the eventLogging service from TCP? For Example: For TCP I should only have net.tcp://localhost:9001/ABC/mex net.tcp://localhost:9001/ABC/eventLogging For HTTP http://localhost:9002/ABC/stats http://localhost:9002/ABC/mex When I connect with any of the base address (using the WCF Test Client) I'm able to access all the services? Like when I connect with net.tcp://localhost:9001/ABC I'm able to use the services which are offered on the HTTP binding. Why is that so? <system.serviceModel> <services> <service behaviorConfiguration="ABCServiceBehavior" name="ABC.Data.DataServiceWCF"> <endpoint address="eventLogging" binding="netTcpBinding" contract="ABC.Campaign.IEventLoggingService" /> <endpoint address="mex" binding="mexTcpBinding" bindingConfiguration="" contract="IMetadataExchange" /> <endpoint address="stats" binding="basicHttpBinding" contract="ABC.Data.IStatsService" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:9001/ABC" /> <add baseAddress="http://localhost:9002/ABC" /> </baseAddresses> </host> </service> </services> <behaviors> <serviceBehaviors> <behavior name="ABCServiceBehavior"> <serviceMetadata httpGetEnabled="false" /> <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel>

  • EDM -> POCO -> WCF (.NET4) But transferring Collections causes IsReadOnly set to TRUE

    - by Gary B
    Ok, this may sound a little 'unorthodox', but...using VS2010 and the new POCO t4 template for Entity Framework (http://tinyurl.com/y8wnkt2), I can generate nice POCO's. I can then use these POCO's (as DTO's) in a WCF service essentially going from EDM all the way through to the client. Kinda what this guys is doing (http://tinyurl.com/yb4bslv), except everything is generated automatically. I understand that an entity and a DTO 'should' be different, but in this case, I'm handling client and server, and there's some real advantages to having the DTO in the model and automatically generated. My problem is, that when I transfer an entity that has a relationship, the client generated collection (ICollection) has the read-only value set, so I can't manipulate that relationship. For example, retrieving an existing Order, I can't add a product to the Products collection client-side...the Products collection is read-only. I would prefer to do a bunch of client side 'order-editing' and then send the updated order back rather than making dozens of server round trips (eg AddProductToOrder(product)). I'd also prefer not to have a bunch of thunking between Entity and DTO. So all-in-all this looks good to me...except for the read-only part. Is there a solution, or is this too much against the SOA grain?

  • Problems with WCF reliable session (reliable messaging)

If I disable the reliableSession on the client I get this message: The action is not supported by this endpoint. Only WS-ReliableMessaging February 2005 messages are processed by this endpoint. So it seems that the server is configured correctly for RM. I cannot find anything valuable about the error I get so I don't know how to fix this. Any ideas what can be wrong? Thank in advance, Rob

  • WCF Ria Services Error : Load operation failed for query 'GetTranslationProgress'

    - by Manoj
    Hello, I am using WCF Ria Services beta in my silverlight application. I have a long running task on the server which keeps writing its status to a database table. I have a "GetTranslationProgress" Ria Service Query method which queries the state to get the status. This query method is called continuously at a regular interval of 5 seconds until a status = Finished or Error is retrieved. In some cases if the task on the server is running for a long duration 2-3 minutes then I receives this error:- Load operation failed for query 'GetTranslationProgress'. The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error. at System.Windows.Ria.OperationBase.Complete(Exception error) at System.Windows.Ria.LoadOperation.Complete(Exception error) at System.Windows.Ria.DomainContext.CompleteLoad(IAsyncResult asyncResult) at System.Windows.Ria.DomainContext.<c_DisplayClass17.b_13(Object ) The error occurs intermittently and I have no idea what could be causing this error. I have checked most of the forums and sites but I have not been able to find out any solution to this issue. Please help.

  • Consume a WCF Web Service in Sharepoint Services 3.0

    - by Filip Ekberg
    I've seen this question and since it doesn't answer my question and the topic is fairly miss-leading in my opinion, I feel the urge to ask this again. I have a Sharepoint Webpart that I deploy using Visual Studio Sharepoint Tools 1.2 to a Sharepoint Services 3.0 instance on my local Windows 2003 server. All works great, however, as soon as I add a WCF Service it won't run the code. All I get is a File not found error. I've added this to my Web.Config which is a copy of App.Config <system.serviceModel> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_Services_xxxService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Mtom" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://localhost:1196/xxxService.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ervices_xxxgService" contract="xxxService.TestService" name="BasicHttpBinding_ServicesxxxService" /> </client> </system.serviceModel> I cannot even do using(var proxy = new xxService.TestService()), If that line is added, the new dll is not added to Sharepoint Services. Any suggestions? I also found this blog post and this forum thread, don't think they are too helpful though.

    Hi all. After complete of asynchronous call to WCF service I want set success message into session and show user the notification .

  • WCF/MSMQ Transport Security with Certificates

    - by user104295
    Hi there, my goal is to secure the communication between MSMQ Queue Managers – I don’t want unknown clients sending messages to my MSMQ server. I have spent many hours now trying to get Transport security working for the net.msmq binding in WCF, where MSMQ is in Workgroup mode and the client and server do not have Active Directory… so I’m using certificates. I have created a new X.509 certificate, called Kristan and put it into the “Trusted people” store on the server and into the My store of Current User of the client. The error I’m getting is: An error occurred while sending to the queue: Unrecognized error -1072824272 (0xc00e0030).Ensure that MSMQ is installed and running. If you are sending to a local queue, ensure the queue exists with the required access mode and authorization. Using smartsniff, I see that there’s no attempted connection with the remote MSMQ, however, it’s an error probably coming from the local queue manager. The stack trace is: at System.ServiceModel.Channels.MsmqOutputChannel.OnSend(Message message, TimeSpan timeout) at System.ServiceModel.Channels.OutputChannel.Send(Message message, TimeSpan timeout) at System.ServiceModel.Dispatcher.OutputChannelBinder.Send(Message message, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation) at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message) The code:- EndpointAddress endpointAddress = new EndpointAddress(new Uri(endPointAddress)); NetMsmqBinding clientBinding = new NetMsmqBinding(); clientBinding.Security.Mode = NetMsmqSecurityMode.Transport; clientBinding.Security.Transport.MsmqAuthenticationMode = MsmqAuthenticationMode.Certificate; clientBinding.Security.Transport.MsmqProtectionLevel = System.Net.Security.ProtectionLevel.Sign; clientBinding.ExactlyOnce = false; clientBinding.UseActiveDirectory = false; // start new var channelFactory = new ChannelFactory<IAsyncImportApi>(clientBinding, endpointAddress); channelFactory.Credentials.ClientCertificate.SetCertificate("CN=Kristan", StoreLocation.CurrentUser, StoreName.My); The queue is flagged as ‘Authenticated’ on the server. I have checked the effect of this and if I turn off all security in the client send, then I get ‘Signature is invalid’ – which is understandable and shows that it’s definitely looking for a sig. Are there are special ports that I need to check are open for cert-based msmq auth? thanks Kris

  • WCF Service Exception

    - by Maciek
    Hiya, I'm currently working on an Silverlight 3 project, I'm using 2 machines to test it. "harbinger" is the web server running Win7 + IIS . I've deployed the webpage and the WCF webservice to that machine. I've entered the following url's in my browser : http://harbinger:43011/UserService.svc http://harbinger:43011/UserService.svc?wsdl and got pages load expected contents for both Next I've decided to check if I can call the webservice from my machine, I've added the ServiceReference, executed a call to one of the methods and .... BOOM : System.ServiceModel.CommunicationException was unhandled by user code Message="An error occurred while trying to make a request to URI 'http://harbinger:43011/UserService.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services.

  • Client WCF DataContract has empty/null values from service

    - by Matt
    I have a simple WCF service that returns the time from the server. I've confirmed that data is being sent by checking with Fiddler. Here's the result object xml that my service sends. <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Body> <GetTimeResponse xmlns="http://tempuri.org/"> <GetTimeResult xmlns:a="http://schemas.datacontract.org/2004/07/TestService.DataObjects" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <a:theTime>2010-03-26T09:14:38.066372-06:00</a:theTime> </GetTimeResult> </GetTimeResponse> </s:Body> </s:Envelope> So, as far as I can tell, there's nothing wrong on the server end. It's receiving requests and returning results. But on my silverlight client, all the members of the returned object are either null, blank or a default vaule. As you can see the server returns the current date and time. But in silverlight, theTime property on my object is set to 1/1/0001 12:00 AM (default value). Sooo methinks that the DataContracts do not match up between the server and the silverlight client. Here's the DataContract for the server [DataContract] public class Time { [DataMember] public DateTime theTime { get; set; } } Incredibly simple. And here's the datacontract on my silverlight client. [DataContract] public class Time { [DataMember] public DateTime theTime { get; set; } } Literally the only difference is the namespaces within the application. But still the values being returned are null, empty or a .NET default. Thanks for you help!

  • WCF Datacontract, some fields do not deserialize

    - by jhersh
    Problem: I have a WCF service setup to be an endpoint for a call from an external system. The call is sending plain xml. I am testing the system by sending calls into the service from Fiddler using the RequestBuilder. The issue is that all of my fields are being deserialized with the exception of two fields. price_retail and price_wholesale. What am I missing? All of the other fields deserialize without an issue - the service responds. It is just these fields. XML Message: <widget_conclusion> <list_criteria_id>123</list_criteria_id> <list_type>consumer</list_type> <qty>500</qty> <price_retail>50.00</price_retail> <price_wholesale>40.00</price_wholesale> <session_id>123456789</session_id> </widget_conclusion> Service Method: public string WidgetConclusion(ConclusionMessage message) { var priceRetail = message.PriceRetail; } Message class: [DataContract(Name = "widget_conclusion", Namespace = "")] public class ConclusionMessage { [DataMember(Name = "list_criteria_id")] public int CriteriaId { get; set;} [DataMember(Name = "list_type")] public string ListType { get; set; } [DataMember(Name = "qty")] public int ListQuantity { get; set; } [DataMember(Name = "price_retail")] public decimal PriceRetail { get; set; } [DataMember(Name = "price_wholesale")] public decimal PriceWholesale { get; set; } [DataMember(Name = "session_id")] public string SessionId { get; set; } }

  • WCF Mono - BasicHttpBinding with SSL

    - by TheNextman
    I'm trying to port an existing WCF client application to run on Linux under Mono. Right now I'm testing everything out, figuring out what works on Mono and what doesn't. The client makes a super simple call over basicHttpBinding. It works great, until I enable SSL (that is, specify BasicHttpSecurityMode.Transport in the binding). Running on .NET in Windows, it works great Running on Mono on Ubuntu 9.10 / Mono 2.6 I get the following error: Exception in async operation: System.Net.WebException: Error getting response stream (Write: The authentication or decryption has failed.): SendFailure --- System.IO.IOException: The authentication or decryption has failed. --- Mono.Security.Protocol.Tls.TlsException: Invalid certificate received from server. Error code: 0xffffffff800b010a I've read the Mono security FAQ here: http://www.mono-project.com/FAQ:_Security; however the SSL certificate on the server is from a root CA (a purchased certificate) - issued by Equifax Secure Certificate Authority. I ran the TlsTest tool on the Ubuntu install against the .svc URL and there are no problems/errors. Also I can hit the service fine in Firefox (no security warnings). What am I missing? Thanks in advance, Richard

  • WCF - CODEGEN: Generating message contract since message FileRequest has headers

    - by Tri Q
    I am aware that there is a similar question here with no solution. I'm working on a WCF streaming service over HTTP. Here are my MessageContract [MessageContract] public class FileRequest { #region Message Header [MessageHeader(MustUnderstand = true)] public Credential Credentials { get; set; } #endregion #region Message body [MessageBodyMember(Order = 1)] public FileInfo FileInfo { get; set; } #endregion #region Ctor // ... #endregion } [MessageContract] public class FileRequestResponse { #region Message Header [MessageHeader(MustUnderstand = true)] public FileInfo FileHeader { get; set; } [MessageHeader(MustUnderstand = true)] public OperationResult<bool> OperationResult { get; set; } #endregion #region Message Body [MessageBodyMember] public Stream FileStream { get; set; } #endregion #region Constructor // ... #endregion } Here is my ServiceContract [ServiceContract(Namespace = "https://service.contract.example.com")] public interface IUpdateService { [OperationContract(Action = "GetUpdates")] OperationResult<List<FileInfo>> GetUpates(ApplicationInfo applicationInfo, Credential credential); [OperationContract(Action = "GetFile")] FileRequestResponse FileRequest(FileRequest fileRequest); } Now the question is why I am getting this error: // CODEGEN: Generating message contract since message FileRequest has headers When I add my service reference. The end result is that the service contract wraps the FileRequest operation into a wrapper which I do not want. public FileInfo FileRequest(Credential Credentials, FileInfo, out OperationResult<bool> OperationResult, out System.IO.Stream FileStream) NOTE: I have not checked the "Always generate message contracts" in the service reference.

  • WCF timeout exception on calling service on 11th time

    - by Sergej Andrejev
    I'm creating a WCF service and stumbled with request timeout problem. When I load test the service the 11th call always fails with "System.Net.WebException: The operation has timed out". I have read that would happen if serviceThrotling is set to defaults so I added following lines to my service configuration file <behavior name="ServiceBehavior"> <!-- ... --> <serviceThrottling maxConcurrentCalls="100" maxConcurrentSessions="100" maxConcurrentInstances="100" /> </behavior> But this doesn't help. I thought that closing the proxy might be a problem, but I do close all proxies. try { response = service.GetCustomerHdQuotes(request); } finally { try { if (service.State != CommunicationState.Faulted) service.Close(); else service.Abort(); // Abort if the State is Faulted. } catch (Exception) { service.Abort(); } } I also have an idea that inside service some resources pile up preventing service to accept new connections, but the fact that this is always 11th request points that this is more likely due to some configuration problems. Can anybody help me with that?
