Cyclic dependency with Castle Windsor IoC for NHibernate ISession

Question

I am using Castle Windsor for my IoC along with NHIbernate in an ASP.NET MVC app. It works great registered as follows (with one exception):

container.Regist         


        

Answer 1

Try to add a dependency on Func< ISession > in your interceptor class

public class CustomInterceptor : EmptyInterceptor
{
    private readonly Func<ISession> sessionFunc;
    private ISession session;

    protected ISession Session
    {
        get
        {
            return session ?? (session = sessionFunc());
        }
    }

    public CustomInterceptor(Func<ISession> sessionFunc)
    {
        this.sessionFunc = sessionFunc;
    }
}

And registration:

container.Register(Component.For<ISession>().
    LifestylePerWebRequest()
    .UsingFactoryMethod(container =>
    {
        var interceptor = container.Resolve<IInterceptor>();
        return container.Resolve<ISessionFactory>.OpenSession(interceptor);
    }));
container.Register(Component.For<Func<ISession>>()
    .LifestylePerWebRequest()
    .UsingFactoryMethod(container =>
    {
        Func<ISession> func = container.Resolve<ISession>;
        return func;
    }));
