WCF, Service attribute value in the ServiceHost directive could not be found

Question

I\'m trying to host my service with IIS 6 but I keep get this exception.

    Server Error in \'/WebServices\' Application.
----------------------------------         


        

Answer 1

I had the same problem but no clue what caused it. I Solved it by changing from Debug to Release and Run using Debug/Start New Instance. After that, it ran in both Release and Debug. It was magic...

Answer 2

In my case Right Click on Virtual Directory and Select "Convert To Application" worked!

Answer 3

Building the solution before adding the service reference solved my problem.

Answer 4

I had the same Exception, this is due to the Type not correctly mentioned in the .svc file

I corrected with below fix.

if your .svc.cs has class like this

namespace Azh.Services.MyApp
{
    public class WcfApp : FI.IWcfAppService
{
...
}
}

for this the .svc file should look like this

<%@ ServiceHost Language="C#" Debug="true" Service="Azh.Services.MyApp.WcfApp" CodeBehind="WcfApp.svc.cs" %>

Answer 5

I got this error when trying to add the Service reference for the first Silverlight enabled WCF in the same solution. I just build the .Web project and it started working..

Answer 6

Option One:

This message is often due to an IIS 7 config problem. If you are used to creating a virtual directory pointing to the folder where your service resides, that no longer works. Now, you need to use the "Create Application..." option instead.

Other Options:

• WCF: The type provided as the Service attribute could not be found
• The type , provided as the Service attribute value in the ServiceHost directive could not be found.
