Is it possible to inject WindowsIdentity into the constructor of a WCF service?

Question

WCF

Good afternoon.
The question is, is it possible to inject WindowsIdentity (which of ServiceSecurityContext.Current.WindowsIdentity) somewhere with Autofac?

Answer 1

Can. Implement a factory that will lazily pull identity from the context, and resolve this factory in the service constructor. It is necessary to do this lazily, because the service instance is created before authorization, and the service method is called after successful authorization, respectively, at the time the service instance is created, the context will be anonymous or nothing, but there will definitely be something at the time the method is called. Therefore, we pull the factory on the method call and get the value from the context.
