WCF Service Host - Service does not register port if it does not run VS as Administrator

Question

Hello, while trying to run a Servicelibrary type Webservice. WCF Service Host gives me the following bad news :

Please Try Changing the HTTP port to 8733 or running as Administrator. System.ServiceModel.Addressaccessdeniedexception: HTTP could not Register URL http://+:8733/. Your process does not have access Rights to this namespace (see http://go.microsoft.com/fwlink/? Linkid=70353 for Details). --> System.Net.Httplistenerexception: Access denied

If I start Visual Studio as Administrator, I can run the service.

But it has to solve this, without running Visual Studio as an administrator?
