WCF Service - HTTP Error 404.3 Not Found. The page you are requesting cannot be served.

Run-time Error: The page you are requesting cannot be served.

In the previous article I explained about Client is unable to finish the security negotiation within the configured timeout (00:01:00). The current negotiation leg is 3 (00:00:00). 

In this article I will explain about the WCF Service problem with not supported mimetype. It means that when I try to serve a WCF service on IIS in a Windows 8 machine, I get the following error:

"The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map."

Reason behind HTTP Error 404.3?

WCF services don’t run on IIS 8 with the default configuration, because the asp.net, c# webserver doesn’t know, how to handle incoming requests targeting .svc files. 

To resolve this please do the following two configurations in IIS 8.0.

• Add new MIME type from IIS 8 - MIME Types -> Actions -> Add

Enter Extension: .svc, MIME type: application/octet-stream

• Add new HttpHandler from IIS 8 - Handler Mappings - > Add Managed Handler

Enter Request path: *.svc, Type: System.ServiceModel.Activation.HttpHandler, and

Name: svc-Integrated

That's it. Now browse your wcf service from IIS.
