最近在学silverlight toolkit控件，看到代震军老师写的的东东不错，网址：http://www.cnblogs.com/daizhj/archive/2009/02/09/1376181.html

可是当我编程时这段代码老出错误：

Action<Chart> chartModifier = (chart) =>
  {
  Axis dateAxis = new Axis { Orientation = AxisOrientation.Horizontal, Title = "雇员名称", FontStyle = FontStyles.Normal, FontSize = 12f, ShowGridLines = true};
  EmployeeChart.Axes.Add(dateAxis);
  Axis valueAxis = new Axis { Orientation = AxisOrientation.Vertical, Title = "薪水", Minimum = -1000, Maximum = 3000, ShowGridLines = true};
  EmployeeChart.Axes.Add(valueAxis);
  };
就是当编码时new Axis {};老提示我：无法创建抽象类和接口。好郁闷不知怎么回事，那位高手能给解释下不盛感激。不知我是什么环境没配好，还是命名空间没有引用好。我现有的命名空间为：
