~/URL namespace access rights when developing WCF hosts

09 May 2011

Running up a WCF service host on a new address gives this exception:

Unhandled Exception: System.ServiceModel.AddressAccessDeniedException: HTTP could 
not register URL https://+:61100/HelloWorld.svc/. Your process does not have access rights 
to this namespace (see for details). ---> 
System.Net.HttpListenerException: Access is denied

The link (Configuring HTTP and HTTPS on MSDN) is pretty useful, it resolves to here at the moment ( seems to break links at times). In short, on Win7, open an administrator console and run this:

netsh http add urlacl url=https://+:61100/HelloWorld.svc user=DOMAIN\USER

The error messages are pretty cryptic so good luck…
