asp.net-mvc - ASP.Net MVC 错误 - 错误的 IL 格式

Question

我正在关注 ASP.Net MVC "TaskList" example video并单击在 Visual Studio 中运行(大约 14:00 分钟进入视频)，我在浏览器中收到以下错误消息:

Server Error in '/' Application.

Bad IL format.
Description: An unhandled exception occurred during the execution of the 
current webrequest. Please review the stack trace for more information 
about the error andwhere it originated in the code.

Exception Details: System.BadImageFormatException: Bad IL format.

Line 15:             "Default", _

Source File: C:\Users\...\TaskList\TaskList\Global.asax.vb    Line: 14

Version Information:
   Microsoft .NET Framework Version:2.0.50727.1434;
   ASP.NET Version:2.0.50727.1434 

我已经仔细检查了我输入的代码，我错过了什么？

谢谢!

哦!

发现问题，在HomeController.vb :

Public Class HomeController
    Inherits System.Web.Mvc.Controller

    ' Display a list of tasks
    Function Index()
        Return View()
    End Function

    ' Dislpay a form for creating a new task
    Function Create() As ActionResult
        Return View()
    End Function

    ' Adding a new task to the database
    Function CreateNew(ByVal task As String) As ActionResult
        ' add the new task to the database
        Return RedirectToAction("Index")
    End Function

    ' Mark a task as complete
    Function Complete()
        ' database logic
        Return RedirectToAction("Index")
    End Function

End Class

Function Complete()缺少返回类型，它应该是:

    ' Mark a task as complete
    Function Complete() As ActionResult
        ' database logic
        Return RedirectToAction("Index")
    End Function

感谢您的建议，我想下次我需要三重检查我的代码!

(虽然如果编译器指向我的代码会很好，而不是 Global.asax.vb ，这让我认为这是一个配置问题)
