An unhandled exception of type "System.StackOverflowException" occurred in System.Core.dll

In my MVC Asp.net project

I have a bootsrapper that initializes a container with unity.

I don't know why, but I get

An unhandled exception of type "System.StackOverflowException" occurred in System.Core.dll

I checked twice, and registration is only done in my initializer.

All dependencies are entered only in ctors.

What could be the reason for this?

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);

        Initializer.Initialize();
        BundleConfig.RegisterBundles(BundleTable.Bundles);
    }

Crash after BundleConfig.RegisterBundles(BundleTable.Bundles);

        Initialize();
    }

    public static void Initialize()
    {

            return;

        lock (LockObj)
        {
            IUnityContainer container = defaultContainer;

Without providing the code, I think this is due to circular dependency. Another possible reason is that you have the wrong loop in one of your constructors.

A , B ; B , C , C A, . :

public class A
{
    public A(B b)
    {
    }
}

public class B
{
    public B(C c)
    {
    }
}

public class C
{
    public C(A a)
    {
    }
}
