Unity Application Block 1.2 for Silverlight - December 2008 依赖注入容器。用其来做MVP模式的silverlight会非常的方便，在正式开始MVP模型的学习前先简单的做了一个视图模型ViewModel的演练。
这里是我的代码：
{
public class ChristmasModel : INotifyPropertyChanged
{
private bool _isShow1 = true;
private bool _isShow2 = true;
private bool _isShow3 = true;
private bool _isShow4 = true;
private bool _isShow5 = true;
private bool _isShow6 = true;
private bool _isShow7 = true;
private bool _isShow8 = true;
private bool _isShow9 = true;
private bool _isShow10 = true;
public bool IsShow1
{
get { return this._isShow1; }
set {
if (this._isShow1 != value) {
this._isShow1 = value;
this.RaisePropertyChanged("IsShow1");
}
}
}
public bool IsShow2
{
get { return this._isShow2; }
set
{
if (this._isShow2 != value)
{
this._isShow2 = value;
this.RaisePropertyChanged("IsShow2");
}
}
}
public bool IsShow3
{

this.RaisePropertyChanged("IsShow3");
}
}
}

this.RaisePropertyChanged("IsShow5");
}
}
}

}
}

set

}
}

}
}
}

}
}
