When WCF-Service2 calls WCF-Service3 everything in that application po...

The WCF Starter kit can auto generate a help page based on the REST API. See this: Once you’re using WebServiceHost2, your services will automatically enjoy the benefits of the new automatic help page functionality ( http://msdn.microsoft.com/en-us/library/ee391967.aspx ) However, I am wondering if there is a way to do this w...
We have got WCF services one hosted as windows service (it uses MSMQ binding) and other hosted in IIS. To have resilience we have got 7 servers where WCF is hosted on IIS, and the 3rd party tool randomly sends request to either of the servers.

We have WCF based SOA architecture and ASP.NET web application consume the services hosted. Within each method that needs service call, we create a proxy instance and close when the results are returned. The binding is basicHttpBinding. By default InstanceContextMode is per session, do we need to change this to Percall as we do not requ...
I have a WCF service which uses the named pipe binding. In one part of my code I want to restart this service, so I simply run serviceHost.Close(); serviceHost = new ServiceHost(singletonInstance, uri); serviceHost.Open(); For some reason, the Open call sometimes gives an exception: Cannot listen on pipe name 'net.pipe://localho...
In my case I am using Lucene.Net for search and would like to use single instances of IndexReader and IndexSearcher.

I presume , such a mode should exist. Just triggering WCF service and exiting. Something else will check a log ( database/file ) produced by WCF service. My understanding it is different to asynchronous call where calling application allows to do something else, but still runs some code on completion event. ...
According to MSDN http://msdn.microsoft.com/en-us/library/ms730137.aspx, Contract behaviors (IContractBehavior types) enable the customization of both the ClientRuntime and DispatchRuntime classes in client and service applications, respectively.

I have written a WCF web service using C# and Visual Studio 2008. When I run it using the built in development web server, I am able to view the results of the various methods by browsing to the URL specified in the [WebGet(UriTemplate = "..")] attribute of the service contract. Specifically, I have a method that matches the "/" URL, a...
I have a Restful WCF service sitting on another server configured with the WebGet attribute to respond to the HTTP Get method. I know the service works correctly because I can call the service directly through the browser and manually do a Get with Fiddler and receive a correct response. I have an Asp.NET project on my local machine th...
Hi all, I developed a proof of concept application that query if WCF support multi-threading.

I have a WCF Service that returns a byte array with a ZIP file (50MB) to any client that requests it. If the zip is very small (say 1MB), the soap response is coming from WCF with the byte array embedded in it.But the response size is very huge even for a 1MB file. If i try the 50MB file to get transferred the Service gets hanged and thr...

I can right click and edit the config file, but I do not see a place where I can inject the user name and password. On the normal client app for this service, we pro...
I have a self hosted Wcf service running on Windows XP and am attempting to use Certificates for message security. This is being done via the service and client config files.
