title: Accessing Azure app configuration in a WCF service
body: <p>We have an on-prem WCF service. Recently we added Azure app config to store some config values. We use certificate based authentication(using service principal) to access Azure App config. The issue is, when we try to connect to the Azure app config from WCF service, we get authentication failed error. We can successfully connect to and access the config values from Azure, using a console app in the same server using the same certificate.
  The service account of WCF has all the access to manage the certificate. Why can't we access Azure app config in WCF service? Are we missing any settings?
  Any help is appreciated.</p>
