在ASP中，HighCharts不包含接受1个参数的构造函数.Net MVC c#

我将HighCharts安装到我的MVC项目中:

Install-Package DotNet.HighCharts

…并尝试运行一个基本的饼状图演示。然而，我在VS2012Express中得到一条消息:

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")用红色下划线，这是注意到的唯一错误。我的控制器代码如下:

有人能看到是什么可能导致这个错误(演示工作很好-但我不能看到任何不同的网络。配置文件等?

谢谢你,

Highcharts chart = new Highcharts("chart")

DotNet.Highcharts.Highcharts chart = new DotNet.Highcharts.Highcharts("chart")
