  • How significant is .NET 3.5 SP1 for WCF/REST?

    - by Edward Tanguay
    I just worked through a book on WCF and was surprised that it didn't even mention REST at all. Was REST an afterthought for WCF that was added in .NET 3.5 SP1 and hence not baked in well or is it well integrated? I assume that Silverlight and XBAPs can consume WCF with no problem or do they have some limitation due to their sandbox environments? I've been reading that some people are having problems getting WCF to play well with XBAP and I would assume there are similar problems with Silverlight.

  • WCF communication using Channel Factory.

    - by Rob Ferno
    How do I get 2 WCF services to communicate with each other using a Channel Factory in C#? Can someone point me in the right direction. Saw a few examples but was confused how the communication really happens and what code needs to be written to support this.

  • WCF service Appdomain details

    - by nettguy
    I am reading WCF book.It states that the client can consume service running on same AppDomain or different application Domain. Suppose I am creating a service in IIS localhost. example localhost\TestService\Service.svc (WCFService Website). and my client is in d:\demo\client (windows form) Does it mean client is running on different AppDomian and Service is running on different Appdomain? How can i have client and service both running on same AppDomain?

  • 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

  • Cannot complete a JSONP call from jQuery to WCF

    - by Dusda
    Okay, I am trying (poorly) to successfully make a JSONP call from jQuery on a test page to a WCF web service running locally, as a cross-domain call. I have, at one point or another, either gotten a 1012 URI denied error, gotten a response but in Xml, or just had no response at all. Currently, the way I have it configured it spits back a 1012. I did not write this web service, so it is entirely possible that I am just missing a configuration setting somewhere, but I've become so frustrated with it that I think just asking on here will be more productive. Thanks guys. Details below. I have a WCF web service with the following method: [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public decimal GetOrderStatusJson(int jobId) I am trying to call this method from a jQuery test page, via a cross-domain JSONP call. <script type="text/javascript"> getJsonAjaxObject( "http://localhost:3960/ProcessRequests.svc/json/GetOrderStatusJson", { "jobId": 232 }); function getJsonAjaxObject(webServiceUrl, jsonData) { var request = { type: "POST", contentType: "application/json; charset=utf-8", url: webServiceUrl, data: jsonData, dataType: "jsonp", success: function(msg) { //success! alert("blah"); }, error: function() { //oh nos alert("bad blah"); } }; $.ajax(request); } </script> Below are the chunks of the web.config I configure for this purpose: <services> <service behaviorConfiguration="MWProcessRequestWCF.ProcessRequestsBehavior" name="MWProcessRequestWCF.ProcessRequests"> <endpoint address="json" behaviorConfiguration="AspNetAjaxBehavior" binding="webHttpBinding" contract="MWProcessRequestWCF.IProcessRequests" /> <endpoint address="" binding="wsHttpBinding" contract="MWProcessRequestWCF.IProcessRequests"> <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="MWProcessRequestWCF.ProcessRequestsBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="AspNetAjaxBehavior"> <enableWebScript/> </behavior> </endpointBehaviors> </behaviors>

  • 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?

  • 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!

  • 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.
