WCF and Entity Framework 6 config file - entity-framework

Question

I've a WCF service defined inside a library and a windows service which self-host this WCF service. I use Entity Framework 6 for Data Layer inside same library.
Who could confirm where I should defined connection string needed for EF?
Inside app.config of my self-hosting Windows Service? ie WindowsService.exe.config...
I want that this connection string would be available for all my WCF clients...
Thanks for your comments!

Ok, finally my issue was not related at all to app.config(s).
I didn't call correctly my WCF service.
To avoid proxies generation/use, I use ChannelFactory() in my WCF Service because I manage both servers and clients. This WCF Service is implemented throw MVVM Light with following code:
ViewModelLocator.cs:
public class ViewModelLocator
{
static ViewModelLocator()
{
ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default);
//Define data access (wcf service) for design mode
if (ViewModelBase.IsInDesignModeStatic)
{
SimpleIoc.Default.Register<IService, Design.DesignDataService>();
}
...
}
WcfServer class:
public class WcfServer : IDisposable
{
//Wcf connection
private ChannelFactory<IService> _wcfFactory = null;
/// <summary>
/// Gets the DataService proxy from MVVMLight SimpleIOC instance.
/// </summary>
public IService DataService
{
get
{
return SimpleIoc.Default.GetInstance<IService>()??null;
}
}
/// <summary>
/// Add a Wcf server for a customer, a url and a server name
/// </summary>
/// <param name="customerName"></param>
/// <param name="serverName"></param>
/// <param name="urlServer"></param>
/// <param name=""></param>
public WcfServer(string customerName, string serverName, string urlServer)
{
_customerName = customerName;
ServerName = serverName;
UrlServer = urlServer;
}
/// <summary>
/// Connect to wcf service
/// </summary>
/// <exception cref="ArgumentNullException">Thrown if a null exception is thrown all over Connect method</exception>

public bool Connect()
{
try
{
...
EndpointAddress endpointAddress = new EndpointAddress(new Uri(UrlServer));
if (_wcfFactory == null)
{
_wcfFactory = new ChannelFactory<IService>(WCFSharedConfiguration.ConfigureBindingWithSimplehttps(), endpointAddress);
//Open ChannelFactory
_wcfFactory.Open();
//Define Faulted handler
_wcfFactory.Faulted += FactoryFaulted;
}
else
//Log + return
if (!ViewModelBase.IsInDesignModeStatic)
{
//If we are not in Design (means blend or VS IDE)
SimpleIoc.Default.Register<IService>(() => _wcfFactory.CreateChannel(), true);
}
}
catch (Exception ex)
{
//Log
throw;
}
return true;
}
/// <summary>
/// Disconnect current channel
/// </summary>
/// <exception cref="TimeoutException">Timeout</exception>
/// <exception cref="CommunicationObjectFaultedException">Faulted Exception on exception from ChannelFactory==>CreateChannel</exception>

public bool Disconnect()
{
...
}
May it helps!
