Injecting data to a WCF service

I have a WCF service that looks like this: (Service-contract attributes omitted for clarity)

public interface IMyService
{
    void LoadBulkData(LoadRequest request);
}

public class MyService : IMyService
{
    IUnityContainer unity = new UnityContainer();
    IDataProvider provider;

    public MyService()
    {
        unity.LoadConfiguration();
        provider = unity.Resolve<IDataProvider>();
    }

    public void LoadBulkData(LoadRequest request)
    {
        // ...
    }
}

As per company policy, Microsoft Unity must be used for DI/IoC. Because this is WCF, I can’t use
constructor injection because the service implementation must use the default, parameterless constructor.

In particular, I don’t like using Unity to resolve the dependency in the constructor. Does anyone
know of a way around this? Also, is there a pattern out there that might better suit my needs
here?

Why not use Property Injection:
