I'm looking to identify a best practice or often used design pattern for WCF communication allow communication to occur and fail over to another service or local service of information if the WCF (or initial service exists) I'm not sure this makes much sense so let me give an example. I'd like this agent to be able to connect to a wcf ...
I'm hosting a Silverlight Business Application Template derived application on an IIS Server. I'm using the built-in Forms Authentication which is working perfectly. Unfortunately, I've added an additional service which has peculiar behavior. If I remote into the server and use the site everything works as expected. If I connect to the ...
I have a simple WCF Rest Service with one method. The interface is defined as: [ServiceContract] public interface IHelloRest { [OperationContract] [WebGet(UriTemplate = "json/hello/{name}", ResponseFormat = WebMessageFormat.Json)] string Hello(string name); } The implementation is defined as: public string Hello(string na...
This is related the following question, but I thought I would create another post so that question would not become too convoluted: When I changed the ResponseFormat to XML, the browser return the response correctly, but if I try to use JSON as the ResponseFormat, it asks me if I want to download the file. Just to see what is in the fi...
Hi there, It seems there is restriction in having the number of out parameters in WCF. My service reference only downloads one out parameter. Example: if the service has the following method: void methodA(out string param1, out string param2) then the service reference will only create methodA(out string param1). Anyone knows h...
I have a WCF server hosting clientaccesspolicy.xml (for Silverlight clients) and I was testing access to it using Internet Explorer. When I accessed it using http://localhost/clientaccesspolicy.xml everything worked correctly, but when I used http://machinename/clientaccesspolicy.xml it wasn't retrieved. I downloaded, installed and ran...
I have several web services. One of this services is used for retrieve a session id (authentication). I pass this id when call other services through SessionInfo. I want to use WCF instead of classic web methods. How can I share one session between several wcf's clients? ...
I have an ASP.NET Ajax service set up using WebSriptServiceHostFactory in the *.svc file - no web.config configuration. In the contract, I'm starting with two very simple methods: [OperationContract()] [WebGet] string GetPersonalInformationLabel(); [OperationContract()] [WebGet] string GetCorporateInformationLa...
In my previous question here i was experiencing difficulties with Authenticating webservices. With the use of the WcfRestContrib library which i found here i was able to solve this issue. I build a small testapplication and the authentication works like a charm. But while i'm implementing this in the webapplication where i want to use t...

I need to develop a WCF server (basically a web service which will eventually run in IIS) and a client application that accesses the service. I have both the client and the server project in the same Visual Studio (2008) solution. What's the recommended way to connect the client to the server during development? Two possible solutions ...
Hi all, In a short view of the IoC and DI .NET libraries I chose to use Ninject2. According to DDD style in: Infrastructure: I have Entity Framework 4.0 .edmx model and the Repository implementation Domain Layer: I have POCO objects and Repository Interfaces (implemented in Infrastructure) Application Services: I have WCF services tha...
I'm attempting to test a [MessageContract] class against an existing sample message, and I'm looking for a way to simplify development by reading the sample message file into an instance of my [MessageContract] class and seeing how it worked out (I'm dealing with a particularly complex contract here, of non-WCF origin). My [MessageContr...

I'm using Topshelf to host a WCF Service as a Windows Service. Even when just running on the console, it takes an exceptionally long time to shut down after I send it a Ctrl-C, and this is mirrored when running as a service. On my local machine, it takes 1ms to call svcHost.Close(new TimeSpan(0)), but 10240ms between the end of my Stop...

The script task will not have access to an app.config file at run time so I need to create the binding manually and set the parameters in code: WSHttpBinding binding = new WSHttpBinding{ Security = new WSHttpSecurity{ ...
How can I add a XML prefix to fields in WCF Message Serialization? I'm connecting up to a Java Spring web service from .NET, and an object that I pass in with parameters is being serialized as you would expect: <MyClass> <field1>Field 1 Value</field1> <field2>Field 2 Value</field2> </MyClass> However, the web service requires tha...
I committed a project to VSTF and then pulled it down locally on another machine. It works fine on my dev box, but on the other machine, the WCF RIA Service link appears to be gone and there is no option to re-add it in the project properties. See image for clarification: http://imgur.com/XIwfB.png What's missing on the other machine? ...
Can someone explain the reason behind this or how it works? IF I do a WebInvoke on the following, it fails (says method not allowed, but if I do a WebGet, it passes). I just want to understand why? [OperationContract] [WebGet(UriTemplate = "login/{username}/{password}", ResponseFormat = ...
