I'm trying to publish a webservice using WCF on IIS7.

I've created a Site for this project, and I created an Application too as [MSDN suggested](http://msdn.microsoft.com/en-us/library/ms733766.aspx#Y521). I can open html files in my browser from the created folder, but I get 404.3 error (The page you are requesting cannot be served because of the extension configuration) if I try to access the svc file of my service. I've read that I should run servicemodelreg to install the missing handlers for the svc files. After I did I got an error saying that the handler has a bad module.

I checked the following stuff every time:

* IIS is turned on
* ASP.NET is turned on
* There is a handler for the svc files

I ran out of ideas...
