MVC3, Unity Framework and Per Session Lifetime Manager Issue

Question

In a simple word I try to create Lifetime manager for Unity framework by using Http Session in my MVC3 project. My sample implementation of lifetime manager is:

Answer 1

My mistake, I should change code of UnityPerSessionLifetimeManager class to be

public class UnityPerSessionLifetimeManager : LifetimeManager
{
    private string sessionKey;

    public UnityPerSessionLifetimeManager(string sessionKey)
    {
        this.sessionKey = sessionKey;
    }

    public override object GetValue()
    {
        return HttpContext.Current.Session[this.sessionKey];
    }

    public override void RemoveValue()
    {
        HttpContext.Current.Session.Remove(this.sessionKey);
    }

    public override void SetValue(object newValue)
    {
        HttpContext.Current.Session[this.sessionKey] = newValue;
    }
}

because when the constructor was called to register type, session state is not ready yet and I already assigned http context of that time to a variable. But in later Get/Set functions session state is ready.
