我将 HighCharts 安装到我的 MVC 项目中：
Install-Package DotNet.HighCharts
...并尝试运行基本的饼图演示。但是，我在 VS2012Express 中收到一条消息：
bm.Controllers.Highcharts' does not contain a constructor that takes 1 arguments
它不喜欢的行是：Highcharts chart = new Highcharts("chart")
new Highcharts("chart")红色下划线，是唯一指出的错误。我的控制器代码如下。
谁能看到可能导致此错误的原因（演示工作正常 - 但我在 web.config 文件等中看不到任何不同？
谢谢，
标记
