Protocol 'net.tcp' is not supported

Question

I am changing my wcf hosting from a Windows service to be hosted in a IIS.

I have added in my solution a wcf Service Appliction and I have added reference to my projects and edited the svc file to this

<%@ ServiceHost Language="C#" Debug="true"
Service="EFG.Acc.CashService.ServiceFactory.CashService" %>

then I have configured web.config and define bindings which will be netTcp binding and endpoints.

I have enabled my IIS website settings to Enabled Protocols to http.nettcp and same exception.

I have an got this exception while browsing my service.svc file:

**protocol 'net.tcp' is not supported. 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 
Exception Details: System.InvalidOperationException: The protocol 'net.tcp' is not supported.

Try read this carefully: http://blogs.msdn.com/b/james_osbornes_blog/archive/2010/12/07/hosting-in-iis-using-nettcpbinding.aspx

• You are using nettcpbinding with http baseAddress

• Add metadata endpoint while testing

• I use nettcp binding with IIS many times and everytime without 'protocolMapping'

• I recommend to use absolute address in baseAddress only (matching protocol net.tcp://!) and relative - in endpoint addresses
