If you’re trying to build REST-enabled services with WCF, you’ll want to use the webHTTP Binding.
This binding defaults to anonymous handling, so if you’re planning on doing any authorization you need to change the binding configuration.
This took me ages to figure out, largely because the webHttp binding is new and not well documented.
To change the binding to support NTLM or Windows authentication, add the following node to the system.servicemodel in your app.config:
Note that you can supply one of five values to the mode attribute: None, Basic, Digest Windows, NTLM, and Certificate.
Once you’ve picked the one you want, in your service definition, specify your new binding from the bindingConfiguration attribute:
And all calls to your REST service should be made with a valid windows network identity.
In your serviceCode, you can retrieve it from the System.ServiceModel namespace:
Oh, and if you’re not comfortable with editing the XML files, or you’d like to explore the dizzying array of other available options in WCF, I also discovered the Microsoft Service Configuration Editor (possibly someone had discovered it before me. ) It lives at C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\SvcConfigEditor.exe. It gives you a simple(ish) visual way to edit WCF Configuration files.
UPDATE: JustinJSmith over at The Cybertopian Chronicle points out that it’s even easier to invoke the config editor – you just right click on your app.config, and select “Edit WCF Configuration” (duh…)

The Infovark Underground is a new blog where Dean and I can unleash our inner nerd, and share some of the technology and experiences we run into as we build Infovark (Yes, we call our product Infovark. It’s got the same name as our company, because we’re all about making things easy to remember and share..)
Unlike our Infovark blog, which details what we’re doing, the underground will get into much more technical detail about how we’re doing it — discussing programming, development and tools.
If that sounds like the kind of stuff you might be interested in, feel free to add our feed to your readers!
