c# - 添加Unity DI框架，现在报错 "The type UmbracoAuthorizeAttribute has multiple constructors of length 1. Unable to disambiguate."

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，我得到:

类型 UmbracoAuthorizeAttribute 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？

尝试将其添加到统一配置中

container.RegisterType<Name of Controller>(new InjectionConstructor());
