为什么CastleWindsor的BeginScope超出范围？

我正在尝试将Castle Windsor添加到我的Web API项目中，并且正在关注此post ，但是在这行代码中遇到编译时错误：

this._scope = container.BeginScope(); 

…作为“ ‘Castle.Windsor.IWindsorContainer’不包含’BeginScope’的定义，并且没有扩展方法’BeginScope’接受类型’Castle.Windsor.IWindsorContainer’的第一个参数可以找到（你是否错过了使用指令或汇编参考？） “

这是整个代码，因此可以在上下文中看到：

 using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Http.Dependencies; using Castle.Windsor; using Castle.MicroKernel.Registration; using System.Web.Http; namespace PlatypiPieServer { public class WindsorDependencyResolver : IDependencyResolver { private readonly IWindsorContainer _container; public WindsorDependencyResolver(IWindsorContainer container) { _container = container; } public IDependencyScope BeginScope() { return new WindsorDependencyScope(_container); } public object GetService(Type serviceType) { if (_container.Kernel.HasComponent(serviceType)) return this._container.Resolve(serviceType); else return null; } public IEnumerable GetServices(Type serviceType) { return _container.ResolveAll(serviceType).Cast(); } public void Dispose() { _container.Dispose(); } } public class WindsorDependencyScope : IDependencyScope { private readonly IWindsorContainer _container; private readonly IDisposable _scope; public WindsorDependencyScope(IWindsorContainer container) { this._container = container; this._scope = container.BeginScope(); } public object GetService(Type serviceType) { if (_container.Kernel.HasComponent(serviceType)) return _container.Resolve(serviceType); else return null; } public IEnumerable GetServices(Type serviceType) { return this._container.ResolveAll(serviceType).Cast(); } public void Dispose() { this._scope.Dispose(); } } public class ApiControllersInstaller : IWindsorInstaller { public void Install(Castle.Windsor.IWindsorContainer container, Castle.MicroKernel.SubSystems.Configuration.IConfigurationStore store) { container.Register(Classes.FromThisAssembly() .BasedOn() .LifestylePerWebRequest()); } } } 

BeginScope在哪里？ 它被弃用了吗？

这是一种扩展方法。 您需要导入Castle.MicroKernel.Lifestyle命名空间。
