This problem has defeated my attempts at Google, so here goes. We were having an issue getting data from a WCF service (just lookup data, so we enabled it for HTTP GET requests). Every once in while it will return a 404. The stack trace does NOT appear to have WCF in the mix - the StaticFileHandler appears to be attempting to serve it...
All, I have been writting Windows Services for a while in C# deriving from ServiceBase. So far my services are hosted in servers where they usually listen to message queues and process messages. Is there a new way of creating such services in WCF ? Thanks, MK ...

I'm already using a BasicAuthenticationRequestInterceptor with the WCF Rest Starter Kit....

I'm implementing a WCF web service based on WF. This web service consumes other web services which I'm not in charge of. So basically my service workflow contains several Send activities. I'm following the TDD approach, so the service implementation is to be covered by unit tests. I want to test proper invocation of 3rd party services. ...

I have an array of enumerations on a WCF reuqest that comes through as null, no matter what I have tried. The service works apart from the issue with enumerations.

Hi All, Let me try to explain my challenge. I'm building a Silverlight app which will be using a WCF service. The WCF service returns a list of users and roles (and lots more but trying to keep it simple). In the SL app I need to fill several comboboxes with lists of users and roles.

I have a requirement (govt client) to turn off all authentication schemes (No anon, NTLM, digest, basic, etc) in IIS6 and enable client certificates only. This part is non-negotiable. This WCF web service provides the data to a Silverlight client. With Basic authentication is on, everything works peachy. When it is turned off, we get...
OK, the situation is we have a class, PatientDto, and a DynamicProxy generated by Castle, PatientDtoProxy. We're using this proxy in the Silverlight client, then want to send it back to the server via a WCF service call. The WCF service Contract expects a PatientDto (ie not the proxy) and, as expected, blows up if you try to send anyth...

I'm making my first WCF Service and I am unsure which route I should take with stored procedures and Linq to Sql.

I guess I'm a little confused... ...
