Get Windows Username in WCF service method

For configuring windows authentication in WCF service, please refer my previous blog Windows Authentication in WCF

In some scenario, we need to find out the user name who calls WCF service method. You can find out current logged in user who called WCF service method using below code:


OperationContext.Current.ServiceSecurityContext.WindowsIdentity.Name


The above property will return logged in user name with domain name. For example, it returns “DOMAIN\USER”.
