What is the starting point for a WCF Library app?

Question

Where is the best place to put code for when a WCF service is just started up? Similar to Page_Load in a web application.

Answer 1

The service implementation constructor would be the obvious place but it also depends on your hosting model

1) run once code: IIS hosting = global.asax; self-hosting = Main / OnStart

2) run once per service instance: constructor of service class

3) Something more exotic: implement IInstanceProvider

Answer 2

In the class constructor of the service implementation.
