We have a WCF (Windows Communication Foundation) client and service application. We're using Windows Authentication with Kerberos. The issue is that the service may be run under one of many accounts (maybe Network Service, maybe a specific user account -- depends on the IT group). This account is not not likely to change daily, but ...

My concern is that for each of their methods, only the HTTP protocol POST has been specified. This is true whether the actual method is responsible for getting, updating or creating records.

Hi guys! I'm working in a WCF project and we need to reuse some legacy components from vb6. In the service, we need to mantain state for each user as we need to store one COM Interop object (per user) which is costly to construct. The project can grow in the future so it's possible we may need to use StateServer/SqlServer-based sessio...

Is there any way to...
