UnityContainer不会沿着所有异常路径警告处理

Question

请你帮我一个警告：

 Warning    CA2000  In method 'UnityConfig.UnityConfig()', object 'container' 
 is not disposed along all exception paths. Call System.IDisposable.Dispose on 
 object 'container' before all references to it are out of scope.

我的代码：

private static Lazy<IUnityContainer> container = new 
Lazy<IUnityContainer>(() =>
    {
        var container = new UnityContainer();
        RegisterTypes(container);
        return container;
    });

我有UnityWebApiActivator类和方法：

public static void Shutdown()
{
    var container = UnityConfig.GetConfiguredContainer();
    container.Dispose();
}
