title: How to add net.tcp to the "Enabled protocols" by using a WIX 3.5 project/setup?
body: <p>We have a few MSI packages (generated by WIX) that install WCF services. Most of these services need net.tcp for their endpoint bindings.</p>
  
  <p>I'd like to make our deployment life easier and automate the process of adding net.tcp.
  I already know the WixIisExtension.dll and make use of its useful functions (create web site, virt. directory, etc.).</p>
  
  <p>Can I use the WixIisExtension to enable the net.tcp protocol?
  If not, how can I achieve that?</p>
