Castle Windsor 代理、隐式接口和 WPF 绑定

我正在尝试使用 Castle Windsor 动态代理实现 WPF ViewModel。我的想法是，我想提供一个接口（下面的 IPerson 应该足以作为示例）、一个具体的支持类和一个拦截器（用于提供 INotifyPropertyChanged 的​​自动实现）。拦截器的实现在这里：http://www.hightech.ir/SeeSharp/Best-Implementation-Of-INotifyPropertyChange-Ever http://www.hightech.ir/SeeSharp/Best-Implementation-Of-INotifyPropertyChange-Ever

我看到的问题是，当我将模型绑定到 WPF 控件时，控件不会将模型视为实现 INotifyPropertyChanged。我相信（但不确定）这是因为 Windsor 显式实现了接口，而 WPF 似乎期望它们是隐式的。

有什么方法可以使这项工作起作用，以便拦截器捕获模型的更改并将其提升到模型吗？

所有版本的库都是最新的：Castle.Core 2.5.1.0 和 Windsor 2.5.1.0

代码如下：

// My model's interface
public interface IPerson : INotifyPropertyChanged
{
    string First { get; set; }
    string LastName { get; set; }
    DateTime Birthdate { get; set; }
}

// My concrete class:
[Interceptor(typeof(NotifyPropertyChangedInterceptor))]
class Person : IPerson
{
    public event PropertyChangedEventHandler PropertyChanged = (s,e)=> { };
    public string First { get; set; }
    public string LastName { get; set; }
    public DateTime Birthdate { get; set; }
}

// My windsor installer
public class Installer : IWindsorInstaller
{
    public void Install(IWindsorContainer container, IConfigurationStore store)
    {
        container.Register(
            Component.For<NotifyPropertyChangedInterceptor>()
            .ImplementedBy<NotifyPropertyChangedInterceptor>()
            .LifeStyle.Transient);
        container.Register(
            Component.For<IPerson, INotifyPropertyChanged>()
            .ImplementedBy<Person>().LifeStyle.Transient);
    }
}

所以答案相当简单......来自的代码http://www.hightech.ir/SeeSharp/Best-Implementation-Of-INotifyPropertyChange-Ever http://www.hightech.ir/SeeSharp/Best-Implementation-Of-INotifyPropertyChange-Ever将拦截器定义为：

public class NotifyPropertyChangedInterceptor : IInterceptor
{
    private PropertyChangedEventHandler _subscribers = delegate { };

    public void Intercept(IInvocation invocation)
    {
        if (invocation.Method.DeclaringType == typeof(INotifyPropertyChanged))
        {
            HandleSubscription(invocation);
            return;
        }

        invocation.Proceed();

        if (invocation.Method.Name.StartsWith("set_"))
        {
            FireNotificationChanged(invocation);
        }
    }

    private void HandleSubscription(IInvocation invocation)
    {
        var handler = (PropertyChangedEventHandler)invocation.Arguments[0];

        if (invocation.Method.Name.StartsWith("add_"))
        {
            _subscribers += handler;
        }
        else
        {
            _subscribers -= handler;
        }
    }

    private void FireNotificationChanged(IInvocation invocation)
    {
        var propertyName = invocation.Method.Name.Substring(4);
        _subscribers(invocation.InvocationTarget, new PropertyChangedEventArgs(propertyName));
    }
}

就我而言，InvocableTarget 根本不是作为第一个参数传递给 PropertyChanged 的​​正确实体（因为我正在生成代理）。将最后一个函数更改为以下内容解决了问题：

private void FireNotificationChanged(IInvocation invocation)
{
    var propertyName = invocation.Method.Name.Substring(4);
    _subscribers(invocation.Proxy, new PropertyChangedEventArgs(propertyName));
}
