Ok, this may be a newbie question but what is the difference between these two?


Seems both of these return the client user id in a WCF service.

The most common implementation in .NET to get authenticated Windows account under which process is running is to get via WindowsIdentity.GetCurrent()

WCF stores information about the identity of the remote client via System.ServiceModel.ServiceSecurityContext class. It’s two most important properties are:
- PrimaryIdentity – This is the identity used by the remote party for authentication while accessing the service.
- WindowsIdentity – This is the WindowsIdentity object representing the Windows Account information used for Windows Authentication.

We can access the ServiceSecurityContext instance from WCF service operation using the static Current property of ServiceSecurityContext class, i.e.: ServiceSecurityContext.Current

Thus, WindowsIdentity is at basic level and a part of identity when used via WCF.
For full details, refer: Identity & ServiceSecurityContext in WCF[^]
