Answer 1

Try using webHttpBinding in your endpoint instead of the wsHttpBinding, or add it as an additional one and change the address. I use a bindingNamespace in my project, but I don't think you need it.

    <endpoint address="XMLService"
              binding="webHttpBinding"
              behaviorConfiguration="restXMLBehavior"
              contract="DRLExternalList.ILeaveManagement">
    </endpoint>

Add an Endpoint Behavior

  <endpointBehaviors>
    <!-- Behavior for the REST endpoint -->
    <behavior name="restXMLBehavior">
      <webHttp helpEnabled="true"/>
    </behavior>
  </endpointBehaviors>

I also annotate the OperationContract slightly differently, but it shouldn't make all that much of a difference. I'll give it to you just in case...

[WebGet(UriTemplate = "/GetLeaveDetails", ResponseFormat = WebMessageFormat.Xml)]

To call the service, it would look like this using the XMLService endpoint name:

http://myWebHost.com/WebService/MyService.svc/XMLService/GetLeaveDetails

Hosting an wcf service into a website issue : System.ArgumentException: ServiceHost only supports class service types

the above link helped me to solve my issue.

<%@ ServiceHost Language="C#" Debug="true" Service="restleave.ProductRESTService" %>
