I have this piece of code to set up Umbraco Vault and initialize my Simple Injector IoC container:

public class AxioApplicationStartup : ApplicationEventHandler
    {
        protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {            
            Vault.RegisterViewModelNamespace("Axiometrics.Web.ViewModels", "Axiometrics.Web");
            DefaultRenderMvcControllerResolver.Current.SetDefaultControllerType(typeof(VaultRenderMvcController));
        }

        protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
            base.ApplicationStarted(umbracoApplication, applicationContext);

            SimpleInjector.Container container = new SimpleInjector.Container();
            container.Options.DefaultScopedLifestyle = new WebRequestLifestyle();
            //container.Register<ILogger, FileLogger>();
            container.RegisterMvcControllers(Assembly.GetExecutingAssembly());
            container.RegisterMvcIntegratedFilterProvider();
            container.Verify();
            DependencyResolver.SetResolver(
            new SimpleInjectorDependencyResolver(container));
        }
    }

If I run it as is, I receive this error: "An MVC filter provider has already been registered for a different Container instance. Registering MVC filter providers for different containers is not supported by this method." which is happening on this line: container.RegisterMvcIntegratedFilterProvider();

If I comment out this line of code that has container.RegisterMvcIntegratedFilterProvider(); and rerun, then I receive this error: "No registration for type VaultRenderMvcController could be found and an implicit registration could not be made. Please note that the container instance you are resolving from contains no registrations. Could it be that you accidentally created a new -and empty- container? For the container to be able to create VaultRenderMvcController it should have only one public constructor: it has 2. See https://simpleinjector.org/one-constructor for more information."

I have no idea how to solve this problem, but my guess is either Umbraco or the Vault component is using another IoC container internally that is causing conflicts with my Simple Injector initialization.

Could you please help me solve this problem? Thanks!
