Multiple constructors accepting all given System.Collections.Generic.List

出现上述错误的原因是给的List未定义或未找到

在学习ASP.Net Core Razor Page时，使用了ViewModel,按照mvc的逻辑，更改了View的model类型，

系统报上述错误，是自己理解错误，在Razor Page中model应该为IndexModel之类的。自己逻辑有问题；

@page
@model ContosoUniversity.Pages.Courses.IndexModel
//这里应该是IndexModel,后面使用model.CourseVM，访问自定义的视图模型
//这里误写为 List<ContosoUniversity.Model.CourseVM,出现上述错误

@{
    ViewData["Title"] = "Courses";
}
