When trying to access the Sitecore Configuration Factory to read a setting while configuring services in the IoC container the below exception is thrown.

public class ServicesConfigurator : IServicesConfigurator
{
    public ServicesConfigurator()
    {
        Sitecore.Configuration.Factory.GetConfiguration();
    }
}

I know, that this is because the configuration factory itself is configured in the container, and is not yet available, so the question is, how do I access values from the Sitecore configuration, before the configuration factory is available through the container? Accessing the factory through the Service Locator throws the same exception, eventhough the factory is already registered at this point.

###Source Error:

##Recursive upgradeable lock acquisitions not allowed in this mode. Sitecore.Configuration.Factory.GetConfiguration();
