I'm using the [WebGet] attribute to query a REST API on a web server. Every so often (because the API is still under development) I get back an HTML document in the form of an HTTP/500 error instead of the XML I want. Here's an example of my operation contract: [WebGet(UriTemplate = "search/?api_key={key}&query={query}", BodyStyle =...
I'm planning to build a set of web services which are going to use geneva-based custom STS to authenticate users. Both STS and relying services will belong to the same party, so the whole goal of going to federated security is providing Single Sign-On point and retrieving all the authorization information only once. Both STS and relying ...
I've been designing web services for quite a while now but never had to expose a 'complicated' WCF service until recently. I was baffled at the apparent lack of "proper support" in WCF for abstract types. Sure - you can USE them - sure you can get them to 'work'... you just don't end up with what you WANT... The first problem is that...
I have some WCF services that are hosted in a windows service. Yesterday I looked at Task Manager and noticed that the CPU time for my windows service process was over 5 hours, while the majority of all other processes were at 0. What does that mean?

Background: This is really a general best-practices question, but some background about the specific situation might be helpful: We are developing a "connected" application for the iPhone.

How do you secure a Silverlight-Enabled WCF Web Service with SSL? I have tried setting it up similar to a regular WCF service secured by SSL, but it doesn't seem to work. What do you set in the Web.Config, and what do you set in the Silverlight's ServiceReferences.ClientConfig? I noticed that in the ServiceReferences.ClientConfig file...

From most of the reading I've done on OpenID, it seems a browser may be required. I'm writing a WCF app and wanted to use OpenID as the authentication method, but my app is not a web app. Is it possible to use WCF and OpenID together without requiring a web browser? ...
