I have a WCF Service hosted as Windows Service and client is an ASP.Net application consuming WCF Service methods.
In process of implementing security, I am confused over which among netTcpBinding/wsHttpBinding will be suitable for my case.
Most likely all the applications in scene (WCF Service, Windows Service, ASP.Net Website) will be sitting on different servers in our office, thus in an Intranet. ASP.Net website will be accessed by users over Internet.
Though, I can always use wsHttpBinding here, will it be suitable to set the service endpoint using netTcpBinding in my case?
Check this out for a comparison of all the different built in bindings:

As for your case, as long as it's the web server contacting the WCF service and you don't need to provide an endpoint for any external consumers of the service...netTcpBinding should be up to the job.
