Answer 1

The endpoint for your service is not properly configured to receive JSON input. In order for the [WebInvoke] attribute to be honored, your endpoint needs to have the webHttpBinding, and it should also have an endpoint behavior of type <webHttp/>

One easy way to ensure that it's properly configured is to use the Factory attribute on the .svc file. Something like the example below:

<%@ ServiceHost Language="C#" Debug="true"
                Service="YourNamespace.YourServiceClass"
                Factory="System.ServiceModel.Activation.WebServiceHostFactory" %>
