在UnityContainer中找不到Resolve <T>方法

Question

根据MSDN,类的Resolve<T>()方法UnityContainer使用如下:

var controller = container.Resolve<ManagementController>();

但是,我在UnityContainer类定义中找不到该方法.我只能看到:

public class UnityContainer : IUnityContainer, IDisposable
{
    // Other methods
    public object Resolve(Type t, string name, params ResolverOverride[] resolverOverrides);
    public IEnumerable<object> ResolveAll(Type t, params ResolverOverride[] resolverOverrides);
    // Other methods
}

我使用了错误的包裹还是什么？

这些是我安装的包.

using Microsoft.Practices.Unity;
using Microsoft.Practices.Unity.Configuration;

IUnityContainer.Resolve<T>() 是一种扩展方法:
