System.InvalidOperationException：在〜/查看/页/ home.aspx视图必须继承自ViewPage，的ViewPage，ViewUserControl或ViewUserControl派生

解决方案

您可能会在无意中已加载到同一个应用程序的MVC框架的两个版本。为了证实，从下载MVC 2期货<一个href=\"http://aspnet.$c$cplex.com/releases/view/41742\">http://aspnet.$c$cplex.com/releases/view/41742.有这个ZIP文件的文件的 MvcDiagnostics.aspx

1. 复制MvcDiagnostics.aspx到Web项目的根目录。


2. 重现错误。


3. 重现错误后，去/MvcDiagnostics.aspx，看看它是否抱怨（会以粗体红字）关于正在加载的框架的多个版本。该工具应建议一个解决方案，如果是这种情况。

不要忘了从项目中删除MvcDiagnostics.aspx当您完成。

I've just installed MVC2 and I've got a view that looks like this

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Home.Master" Inherits="System.Web.Mvc.ViewPage" %>    
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    Home
</asp:Content>    
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">    
    <h2>Home</h2>    
</asp:Content>

And the controller is just returning the view. But when I run the page I get this error:

System.InvalidOperationException: The view at '~/Views/Page/home.aspx' must derive from ViewPage, ViewPage, ViewUserControl, or ViewUserControl.

解决方案

You might unintentionally have two versions of the MVC framework loaded into the same application. To confirm, download MVC 2 Futures from http://aspnet.codeplex.com/releases/view/41742. There is a file MvcDiagnostics.aspx in this ZIP file.

1. Copy MvcDiagnostics.aspx to the root of your web project.
2. Reproduce the error.
3. After reproducing the error, go to /MvcDiagnostics.aspx and see if it complains (will be in bold red lettering) about multiple versions of the framework being loaded. The tool should suggest a resolution if this is the case.

Don't forget to delete MvcDiagnostics.aspx from your project when you are done.
