The interdependent relationship of dependencies is established
OK I am getting a stack error. The file it came to is located here
using System.Web;
using NHibernate;
using Nichols.Web.App_Start;
namespace Nichols.Web.DependencyResolution
{
public class StructureMapScopeModule : IHttpModule
{
public void Dispose()
{
StructuremapMvc.StructureMapDependencyScope.Dispose();
}
public void Init(HttpApplication context)
{
context.BeginRequest += (sender, e) =>
{
InitializeNestedContainerForRequest();
var session = GetCurrentSession();
session.BeginTransaction();
};
context.EndRequest += (sender, e) =>
{
var session = GetCurrentSession();
if (context.Context.Error == null
&& IsOk(context.Response.StatusCode))
{
session.Transaction.Commit();
}
else
{
session.Transaction.Rollback();
}
DisposeNestedContainerForRequest();
};
}
private ISession GetCurrentSession()
{
var container = StructuremapMvc.StructureMapDependencyScope.CurrentNestedContainer;
return container.GetInstance<ISession>();
}
private void InitializeNestedContainerForRequest()
{
StructuremapMvc.StructureMapDependencyScope.CreateNestedContainer();
}
private void DisposeNestedContainerForRequest()
{
StructuremapMvc.StructureMapDependencyScope.DisposeNestedContainer();
}
private bool IsOk(int statusCode)
{
return statusCode >= 200 && statusCode < 300;
}
}
}
I've looked all over the place and it refers to version 3.0.5 as a possible resolution. Any help is appreciated!
The error I'm getting is located here:
Server Error in '/' Application.

To avoid excluding the dependency relationship between the two directions, you can implement lazy loading as shown below.
private readonly Lazy<IService> _service;
public MainService(Lazy<IService> service)
{
_service=service;
}
Now you can call methods on the service as
_service.Value.Method()
I think this should solve your problem.
