Does Silverlight 3.0 support WebHttpBinding for WCF RESTful services? ...
Exposition (short version at the bottom) The objective is to build a service that I will then consume via jQuery and a standards based web front-end, mobile device "fat-clients," and very likely a WPF desktop application. It seems like WCF would be a good option, but I've never built a RESTful service with WCF, so I'm not sure where to...
I'm developing a windows sidebar gadget that calls out to a wcf service via a javascript xmlhttprequest. If you stop the iis site hosting the service, shouldn't all calls to that service from the client return a 404 or something similar? The gadget and wcf service are running on separate machines. When I stop the iis site hosting the ser...

I am to design a webservice using WCF that yields methods that don't require a session (like static calls, eg: giving back some information about the webservice itsself) and other methods that require a session. furthermore, the session based methods are using Workflows that are supposed to be able to be changed at runtime. my current ...
Hi there, My RESTful WCF Web service appears to break itself if I leave it alone for a while! I can leave my PC with everything working and when I return and test the service with a simple url request it'll offer me the .svc file for download instead of initiating the request on the server! This WCF service sits in it's own IIS Applica...
Hi, I´m creating a ServiceFactory to gain control over inicialization of my services exposed through IIS 7. However I´m surprised by the behavior of ServiceHost. Although I have 0 configuration files for the service, wherever I Initialize a new ServiceHost, like this: var host = new ServiceHost(typeof(MyService), baseAddresses); Nex...
Scenario: I've got an web app that hosts a silverlight app. Silverlight is using the web app to call wcf services. I also have WIF for federated authentication in the mix so the first thing the web app does is it redirects you the the STS to login. Once you login successfully you get a token that is wrapped in an http cookie and sent to...
I have a WCF service hosted within IIS that logs information in a sql server 2008 db. I have successfully tested this within my local IIS and SS2008 db (using an application pool running under my windows id). Now I have moved the database and wcf service to the production server and wondering how to set the security up on the database t...
A co-worker and I are having a discussion about WFC services when the topic of "cost" comes up. The question is this: Given that an IIS-hosted WCF service and a Windows-Service-hosted WCF service do the exact same thing, which service will be more "expensive" with regard to memory and CPU cycles if they both are accepting the same load...
I am trying to enable an additional net.tcp endpoint (which uses Username authentication) for an existing WCF service. The service is hosted in IIS7. Executing a client against the service returns an error that the socket connection was aborted. Enabling tracing against the service reveals the following exception is thrown: System.Arg...
I've set up a WCF web service to be called from my web site. It's working great, but if I request a large amount of data (not sure on the size, but it's easily 3-4 times larger than the "standard" data I'm returning), Cassini (Visual Studio Web Server) just closes the response without sending anything-- no error or anything. Nothing in e...
Hi, I've seen several similar scenarios explained here but not my particular one. I wonder if someone could tell me which direction to go in? I am developing two (and more later) MVC2 apps. There will also be another (thicker) client later on (WPF or Silverlight, TBD). These all need to share the same authentication. For the MVC2 apps...
I have a WCF client/service app that relies on secure communication between two machines and I want to use use x509 certificates installed in the certificate store to identify the server and client to each other.

Hi all, I am struggling with a WCF issue relating to name resolution-or something like so. When I consume a wcf service (netTcpBinding) on an application server via a web application on the web server it doesn't work. Ok it doesn't work in most situations. If you access the web application from the web server itself using localhost or 1...
Hello all. I have found myself responsible for carrying on the development of a system which I did not originally design and can't ask the original designers why certain design decisions were taken, as they are no longer here. I am a junior developer on design issues so didn't really know what to ask when I started on the project which...
