I make calls to a WCF service from my silverlight application. I am doing this asynchronously and I am not blocking execution after making the async. call (that means, I am not using wait-join mechanism frm this page). I do not want the flow to get blocked. However, I would like to detect that the WCF call has gone into a wait state so ...
I am using WCF for the client to access service. I am trying to access the endpoint with TLS (https). I have certificates with both private and public keys. If I have the end point of the service to have the host name same as the certificate name ("Issued To"), then i am able to access the service from the client. If the names of the...

Hi, What measures can you take to 'hide' a WCF service from the public? i.e. even if they know the URL, you don't expose the methods etc. ...
I'm doing some quick Java-.NET interop and have decided on POX with WCF. However, I don't want to -- nor have access to -- deploy to IIS. Would just wrapping it up as a .NET Service be the way to go? (I've built my fair share of Windows services in my years.) Are there any good samples around of this? What handles the HTTP if I'...
Ok, I have a pretty complex silverlight app that gets its data from a WCF service (asp.net hosted service layer) which in turn calls into a data layer that calls stored procedures in a SQL 2005 DB to extract the needed data. So the round trip goes like this: Silverlight App --> WCF Service --> Data Layer --> DB --> Data Layer --> WCF S...
I have a page fetching HTML content from a WCF REST service via AJAX. I started seeing errors on IE to the effect that "This page is accessing information that is not under its control...". For some content, the WCF service will, instead of returning the content directly, return instead an object or iframe tag pointing back to itself w...
Hi everyone, I have an N-tier structure composed of WCF nodes. I need to occasionally pass very large volumes of data from a terminal node to the top node and I would like to avoid deserializing the very large data field during the intermediate hops. I can't pass directly to the top due to our fall over strategy. Is there any way to avo...
This has happened a couple of times to me know. If I add to many OperationContract's to a ServiceContract, the WCF Test Client app throws an exception: "Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata." In the details it continues: Error: Cannot obtain Metadata ...
How do I create a Setup And Deployment project that can run any number of times on a machine without requiring an uninstall? I've created an installer to install a WCF service to an IIS directory. It does more than just xcopy, it asks the users questions to correctly setup web.config. The problem is when it can only be installed once ...
I like instantiating my WCF service clients within a using block as it's pretty much the standard way to use resources that implement IDisposable: using (var client = new SomeWCFServiceClient()) { //Do something with the client } But, as noted in this MSDN article, wrapping a WCF client in a using block could mask any errors tha...
Hi, I developed a WCF service and i have published it with IIS. All goes well inside the local network but when the service is accessed by an external client from the internet, redirected by a firewall, the service generates a local wsdl uri that cannot be solve by the client. Something like this: URI needed: http://external_url/serv...
I encounter a problem with using the WebServiceHostFactory in IIS. "IIS specified authentication schemes 'IntegratedWindowsAuthentication, Anonymous', but the binding only supports specification of exactly one authentication scheme. Valid authentication schemes are Digest, Negotiate, NTLM, Basic, or Anonymous. Change the IIS settings so...
I'm trying to send a POST request to a simple WCF service I wrote, but I keep getting a 400 Bad Request. I'm trying to send JSON data to the service. Can anyone spot what I'm doing wrong? :-) This is my service interface: public interface Itestservice { [OperationContract] [WebInvoke( Method = "POST", UriTemplat...
We are trying to create a cool API using WCF and ICriteria, for example: [ServiceContract] public class ProductService { [OperationContract] public List<Product> Get() [OperationContract] public List<Product> GetByCriteria(Criteria criteria) } We are thinking of using the DetachedCriteria so anyone can send it and we connect this to...
I have a server that handles the database access and a client that consumes the information. The communication from the client to the server is through a WCF service. When the NHibernate POCO is returned from the service are all the objects in the object graph serialized? If so, is there a way to change it? I'm also thinking of not ret...
We've written a WCF service to be used by a Java shop, who is using CXF to generate the adapters. We're not that familiar with Java, but have exposed the service using basicHttpBinding, SSL, and basic authentication. Integration tests show that a .NET client can consume the service just fine. However, the Java shop is having trouble c...
I'm creating a simple Silverlight 2 application - a guestbook. I'm using MSSQL as the data source, I've managed to load the data but I can't find out how to add new rows (messages) to the database. I crawled all the internet but didn't find any working solution. The SCMEssages table has four columns - MessageID, MessageDate, MessageAuth...
Hi, My .net WCF service calls a SSIS package using the Package.Execute(); method. After I call execute, I set pkg.Dispose() and app = null; The memory usage keeps climbing, 100mb to 150mb all the way to almost 300mb. I am recycling the process now, but want to know the source of the problem. Any ideas? Update The application that c...
