I had a complex WCF service based solution working on my PC but due to a problem installing Windows 8.1 I had to \'Refresh\' my PC. Now that I\'ve reinstalled Visual Studio 2012
Another option is to bypass port-specific access control lists and enable the wcfservicehost to run as Administrator.
You can do this by finding the wcfsvchost.exe in your file system (e.g. C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\wcfsvchost.exe), right-clicking the file and selecting 'Compatibility' tab.
In there, you can select 'Run this program as an administrator', if you are an administrator (and you should be if you are rocking stackoverflow ;-)).
Restart Visual Studio, and you should be good to go.
