Problem with WCF Web Service in SP2010

Question

I've followed this tutorial and also this one (tried every possible combination of those) to deploy a custom WCF service in Sharepoint 2010.

But I'm not having any luck. Once the service is deployed, I tried to access it and get the annoying and undescriptive error:

XML Parsing Error: no element found
Location: http://mysharepointsite/_vti_bin/folder/service.svc
Line Number 1, Column 1:

I can't find any description of it. There's nothing in the event log.

Any ideas?

Thank you

UPDATE

The .svc file contains the following:

<%@ServiceHost Language="C#" Debug="true"
    Service="MyNamespace.MyServiceClass, $SharePoint.Project.AssemblyFullName$"
    Factory="Microsoft.SharePoint.Client.Services.MultipleBaseAddressBasicHttpBindingServiceHostFactory, Microsoft.SharePoint.Client.ServerRuntime, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

I've added the .svc extension to the replaceToken section in the .csproj to get the $SharePoint.Project.AssemblyFullName$ replaced by the actual assembly full name.

Follow this steps from this article : http://msdn.microsoft.com/en-us/library/ff521581.aspx

By the way, You can choose to have the WCF without the factory. Just supply the configuration in a separate web.config and place it along with your SVC file.
