C# WCF ChannelFactory BadRequest 400 Error

Question

I have created a simple webservice server, but to call methods from service class in same project i've created a webchannelfactory proxy. Everything it's working fine until i move the project(or exe version) to another machine. I can't figure it out what's going on!

I'm getting this error Message:

The remote server returned an unexpected response: (400) Bad Request.

with Stacktrace:

Code:

WebChannelFactory<Client.IClientService> factory = new WebChannelFactory<Client.IClientService>(hostUri);

Client.IClientService proxy = factory.CreateChannel();

proxy.dosomething();  // Error shout here on Machine2

Thanks in advance

EDIT1: For this example, there's no client-side(i've named Client to this Server). As i said, the code it's working with no errors in another machine(both using localhost).

<?xml version="1.0"?>
<configuration>
      <appSettings>
      <system.serviceModel>
        <bindings>
        </bindings>
    <services>
      <service name="Client.ClientService" behaviorConfiguration="Default">
        <endpoint address="" binding="webHttpBinding" contract="Client.IClientService"></endpoint>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="Default">
          <serviceMetadata httpGetEnabled="true"></serviceMetadata>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>
</configuration>

EDIT2:

On Browser, i got this:

The server encountered an error processing the request. The exception message is 'The type initializer for 'Client.ClientService' threw an exception.'. See server logs for more details. The exception stack trace is:

Problem Solved.

The service make use of a database, so when i copy the project to a new machine i forgot to create a new database.
