在Visual Studio for Mac上运行.NET MVC项目时的System.InvalidOperationException

Question

我正在尝试将我们在Visual Studio 2017社区中开发的项目导入到Visual Studio for Mac中。在构建项目和在数据库中传播数据方面，似乎一切正常，但是当涉及到显示CSHTMl页面时，它会抛出以下异常：

    System.InvalidOperationException
    The view found at '~/Views/Account/login.cshtml' was not created.

Description: HTTP 500.Error processing request.
Details: Non-web exception. Exception origin (name of application or object): System.Web.Mvc.

我读到这是因为Views/Web.config文件错误地引用了MVC的版本，但是它正确地指向了版本5.2.3.0。还有其他人遇到过这个问题吗？

我找到了问题的答案--原来只是由于网址中的大写问题--网址指向的是http://localhost:8080/Account/login，而不是http://localhost:8080/Account/Login。显然，在PC上，这不是问题，但在基于linux的系统上，这是一个问题。在我的例子中，更改是在Web.config中的以下位置进行的：

<system.web>
  <authentication mode="Forms">
    <forms loginUrl="~/Account/Login">
