Maybe Application_Start() ?

>The reason I want to put this in the code is to have the control over it. Everything that most of the people usually put in Global.asax, I put it in my Global class. Then, from Global.asax, the only thing I have to put is the one line you see above. By that, I do not have to worry about setting up web.config wherever I need a Web site or Web service application. I control everything from the framework and that makes it easier to migrate to another development environment when time comes. This Global.asax is to proprietary to .NET.

Fair enough - but you could probably use the machine.config or the root web.config to do that.....
I'd favour web.config because you can change settings on the fly without re-publishing, use hierarchies, build different web.configs for release/debug versions etc. etc....
