Access Denied (System.ComponentModel.Win32Exception) While Calling WCF Service

Question

Hosting the WCF services via a host exe on Windows 8.1 I am getting an AppContainer related error. I cannot find any good documentation on the methods on the top of the stack trace. Kind of grasping at straws here.

Answer 1

So the IIS site was configured to impersonate and that user did not have rights! Spotted the user using Process Monitor. Not surprisingly removing following line allowed things to work as my user, an administrator, has rights just fine.

<system.web>    
    <identity impersonate="true" username="user" password="password" />
</system.web>

It looks like you're attempting to use a named pipe binding and you can't use named pipes in a WinRT based application.
