WCF Web Services Hosting in IIS - Works in VS but Not in IIS

I have a lot of new things in web programming, so my question is about the basics. I am developing a SilverLight application and need to access it from the database. I use LINQ to SQL to retrieve data from a database and the WFC web service to deliver it to my application.

Everything works fine when I run my application in Visual Studio. When you try to publish a web service to IIS, the web service call fails.

To make my question simple, I will focus on a completely new web service. Here are the steps I'm doing:

  • Launch Visual Studio 2008 -> File -> New -> Project -> Web -> WCF Service Application Project Name: MyWcfService

  • Result Visual Studio creates a sample project with the embedded web service "Service1"

  • Rebuild, start with Visual Studio (host on the ASP.NET development server) -> Everything works fine, I see my service under the http://localhost:52489/Service1.svclink

  • Now I want to host this service on my IIS (I have IIS7 on a Vista x86 PC) Visual Studio -> right-click Project -> Publish -> target location -> Create a new web application called "MyWcfService" -> Publish

  • Just to check my folder C:\inetpub\wwwroot\, now it contains a subdirectory of MyWcfService with all the necessary files.

  • Open IE on my PC http://localhost/MyWcfService/Service1.svc

Result:

HTTP Error 404.3 - Not Found The page you requested could not be completed due to the extension configuration. If> the page is a script, add a handler. If you need to download the file, add a MIME card.
