摘要继承成员未实现

Question

我在Visual Studio 2013中创建了一个新的MVC项目,在使用空模板(带模型)和使用布局页面(设置为空)创建视图后,我收到以下内容:

这会导致视图呈现不正确.我试过在其他地方寻找解决方案无济于事.清洁/重建解决方案也无济于事.令人讨厌的是,它是在一个全新的项目中实现的.

有关如何修复的任何想法？

_ViewStart.cshtml

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

我可以向你保证_Layout页面上没有任何时髦的事情发生.

更新

简单地关闭并重新打开解决方案似乎会使错误消失.

页面也很好.在创建一个新项目后,我发生了奇怪的事.我将监视以确定它是否会再次发生.

Answer 1

这是一个很长的镜头,但你可以尝试这个步骤:

• 在解决方案上运行一个干净的
• 使用问题卸载项目
• 删除Visual Studio在 项目旁边生成的.user文件
  
• 用问题重新加载项目
• 构建解决方案

取自这个帖子,也许可以帮到你.值得一试.
