asp.net 5 beta 6 视图错误
Error in view with asp.net 5 beta 6
我在 ASP.net 5 Beta 6 中使用 @model 或 @inject IOptions<AppSettings> AppSettings
时出现错误
DI 似乎是问题所在。
An error occurred during the compilation of a resource required to process this request. Please review the following specific error details and modify your source code appropriately.
/Views/Account/Login.cshtml
The type or namespace name 'LoginViewModel' could not be found (are you missing a using directive or an assembly reference?)
@model LoginViewModel
而且 taghelpers 也没有工作。
主页上的 link 不会转换为真正的 link。请参阅下面生成的 html。
<a id="registerLink" asp-controller="Account" asp-action="Register">Register</a>
我认为它与软件包或启动代码有关。请参阅下面的代码。

由于错误消息表明您可能在视图中缺少 using 语句。如果您希望 using 语句应用于所有视图，那么您可以在 Views 文件夹下创建一个 _ViewImports.cshtml 文件并添加如下内容：
@using MvcSample.Web.Models
@addTagHelper "*, Microsoft.AspNet.Mvc.TagHelpers"
您的标签助手现在也应该开始工作了。
从 ASP.Net 5 Beta 5 开始，MVC 6 项目 有几个重大变化；最初，要在视图中使用的引用包含在名为：
的文件中
_GlobalImport.cshtml
现在已重命名为：
_ViewImports.cshtml
官方公告：https://github.com/aspnet/Announcements/issues/27
Visual Studio 2015 RC 模板尚未更新以反映这些（和其他）重大更改。 ASP.Net 团队声明 ASP.Net 5 的最终版本将在 Visual Studio 2015 发布后以 NuGet 包的形式发布。
有关 beta4（随 Visual Studio 2015 RC 一起提供）和 beta5 之间变化的更深入的答案，关于升级说明，我推荐以下答案，这也与 beta6:
