What is procedure to host WCF webservices

WCF is a flagship product from Microsoft for developing distributed application using SOA. Prior to WCF traditional ASMX Web services were hosted only on Internet Information Services (IIS). The hosting options for WCF services are significantly enhanced from Microsoft .NET Framework 3.0 onwards. In WCF there are three main parts: Service, Endpoints and Hosting Environment. Multiple services can be hosted using a single host process and also the same service type can be hosted in multiple host processes. We can host a WCF service in two ways - Self Hosting and IIS Hosting. Here we will examine Self Hosting along with a comparative discussion of different hosting environments.

elf Hosting Vs IIS Hosting


Let’s look at  the differences between the two hosting types
available for a WCF service.


































Self-Hosting



IIS Hosting



Needs to add code to host the process



Automatic hosting



Host process should be running before client makes a call to the
service.


 




IIS host runs automatically when a client makes a call to the
service.


 




Automatic process recycling not possible



Automatic process recycling not possible




Can   controlled the service lifetime using Open and Close methods



Lifetime cannot be controlled manually.



Easy to deploy



More difficult deployment than  Self-Hosting



 


Protocols Supported
