Download Samples When browsing to a .svc file, the file is not recognized, the browser shows a blank page, or the text of the file is displayed instead of the service's help page as in the following example.
<%@ServiceHost language=c# Debug="true" Service="Microsoft.ServiceModel.Samples.CalculatorService" %>
To correct this you must make sure that aspnet_isapi is enabled as a Web service extension for IIS. You can view and modify this setting using IIS Manager, or by running aspnet_regiis –I –enable from the .NET Framework installation directory. Once you have done so, verify that ASP.NET is running. To do so, place a test .aspx file in the \inetpub\wwwroot directory, and make sure it can be browsed with a browser.
If you installed IIS after Windows Communication Foundation (WCF) was installed you must run the following command:
"%WINDIR%\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe" -r
You must also make sure that the .svc file type is mapped to aspnet_isapi.dll.
