添加了 Unity DI 框架，现在出现错误“类型

Question

我将 Unity DI 框架作为 nuget 包添加到我的 Umbraco 解决方案中。我的统一配置文件如下所示：

public static class UnityConfig

{

    #region Unity Container

    private static Lazy<IUnityContainer> container =

      new Lazy<IUnityContainer>(() =>

      {

          var container = new UnityContainer();

          RegisterTypes(container);

          return container;

      });

    public static IUnityContainer Container => container.Value;

    #endregion

    public static void RegisterTypes(IUnityContainer container)

    {

        container.RegisterType<IHomeViewModelFactory, HomeViewModelFactory>(new PerResolveLifetimeManager());

    }

}

我可以启动网站，但是一旦我尝试访问 Umbraco 后台，我就会得到：

UmbracoAuthorizeAttribute 类型有多个长度为 1 的构造函数。无法消除歧义。

更具体地说，日志文件说：

ERROR Umbraco.Core.UmbracoApplicationBase - An unhandled exception occurred

Unity.Exceptions.ResolutionFailedException: Resolution of the dependency failed, type = 'Umbraco.Web.Mvc.UmbracoAuthorizeAttribute', name = '(none)'.

Exception occurred while: while resolving.

Exception is: InvalidOperationException - The type UmbracoAuthorizeAttribute has multiple constructors of length 1. Unable to disambiguate.

-----------------------------------------------

At the time of the exception, the container was: 

  Resolving Umbraco.Web.Mvc.UmbracoAuthorizeAttribute,(none)

 ---> System.InvalidOperationException: The type UmbracoAuthorizeAttribute has multiple constructors of length 1. Unable to disambiguate.

   at Unity.ObjectBuilder.BuildPlan.Selection.ConstructorSelectorPolicyBase`1.FindLongestConstructor(Type typeToConstruct)

   at Unity.ObjectBuilder.BuildPlan.Selection.ConstructorSelectorPolicyBase`1.SelectConstructor(IBuilderContext context, IPolicyList resolverPolicyDestination)

   at Unity.ObjectBuilder.BuildPlan.DynamicMethod.Creation.DynamicMethodConstructorStrategy.CreateInstanceBuildupExpression(DynamicBuildPlanGenerationContext buildContext, IBuilderContext context)

我该如何解决这个问题？

尝试将此添加到统一配置container.RegisterType<Name&nbsp;of&nbsp;Controller>(new&nbsp;InjectionConstructor());
