添加了Unity DI框架，现在得到错误"The type UmbracoAuthorizeAttribute has multiple constructors of length 1. Unabl

Question

我将Unity DI框架作为nuget包添加到我的Umbraco解决方案中。我的 Unity 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());
}
}

我可以启动该网站，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？

Answer 1

尝试将其添加到 Unity 配置中

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

Answer 2

在UnityConfig.cs中，添加以下语句将解决问题：

container.RegisterType<UmbracoAuthorizeAttribute>(new InjectionConstructor());
