Hosting a .NET 4.0 REST service in IIS 6

Last week I had to deploy a WCF 4.0 REST service on an IIS 6 environment. When I ran this service locally everything worked perfect. In the route table I had configured that my service was accessible at http://localhost/servicename/.

But when i tried to call the service on the server environment, I got nothing back. I knew that IIS by default expects that a request can be mapped to a physical file on disk. So what I could have done was adding an SVC file. But I didn’t need an SVC file on my local machine. I wanted a better solution.

It took me some time but with these steps I got everything working as expected:

  1. Open the IIS  manager. Right click on the VirtualDirectoryName where the service is installed and select Properties. On the Virtual Directory Tab click the Configuration Button. Insert a new WildCard Mapping C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll. Don’t forget to uncheck Verify that file exists.
  2. Go back to the Properties and open Directory Security Tab. In the Authentication and access control click the Edit Button. Uncheck Integrated Windows Authentication.
  3. Reset IIS(really important!).
