IoC Generic Container Interface

A generic interface that can be implemented for different IoC containers. By using the interface switching between container implementations would be easy, particularly helpfull when testing the use of a container.

using System;
using System.Collections.Generic;

namespace IoC
{
    public interface IIoCGenericContainer
    {
        object Resolve(Type t);

        T Resolve<T>();

        T TryResolve<T>();

        IEnumerable<object> ResolveAll(Type t);

        IEnumerable<T> ResolveAll<T>();

        void RegisterType<T>();

        void RegisterType<T>(bool singleton);

        void RegisterType<TFrom, TTo>() where TTo : TFrom;

        void RegisterType<TFrom, TTo>(bool singleton) where TTo : TFrom;

        void RegisterInstance(object instance);

        void RegisterInstance<TInterface>(TInterface instance);

        void RegisterInstance<TInterface>(TInterface instance, bool singleton);
    }
