Dispose for Unit Of Work

Question

I have a code where controller calls service and service use Unit Of Work to handle DB. I have used Unity as dependency injection. I need to dispose unity(dbContext) automatically after request scope ends. I am not getting reference to PerRequestLifetimeManager in UnityCofig.cs. Any pointers?

Are you trying to find the PerRequestLifetimeManager, or do you ask for suggestion on how to dispose your UoW? — smoksnes, Jun 17 '16 at 06:15
Doesn't unity detect if your UoW is disposable and automatically call Dispose when the request is finished? — Neil, Jun 17 '16 at 09:16

Try creating new derived type of lifetime manager

public class PerHttpRequestLifetime : LifetimeManager
{
    // This is very important part and the reason why I believe mentioned
    // PerCallContext implementation is wrong.
    private readonly Guid _key = Guid.NewGuid();

    public override object GetValue()
    {
        return HttpContext.Current.Items[_key];
    }

    public override void SetValue(object newValue)
    {
        HttpContext.Current.Items[_key] = newValue;
    }

    public override void RemoveValue()
    {
        var obj = GetValue();
        HttpContext.Current.Items.Remove(obj);
    }
}

Will this automatically call Dispose on DBContext on call of RemoveValue()? – Pritam Jun 17 '16 at 08:32
Accidentally voted down. Could you please edit the answer so that I can remove it? – smoksnes Jun 19 '16 at 08:43
