taghelpers intellisense在Preview5中不起作用

Question

我下载并安装了最新的.NET Core:

dotnet --version
1.0.0-preview5-004478

我还更新了我的AspNetCore项目的包引用:

<PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp1.1</TargetFramework>
    <PreserveCompilationContext>true</PreserveCompilationContext>
  </PropertyGroup>
  <ItemGroup>
    <Folder Include="wwwroot\" />
  </ItemGroup>
<ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="1.1.0" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc.TagHelpers" Version="1.1.0" />
    <PackageReference Include="Microsoft.NETCore.App" Version="1.1.0" />
    <PackageReference Include="Microsoft.AspNetCore.Diagnostics" Version="1.1.0" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Tools" Version="1.1.0-preview4-final" />
    <PackageReference Include="Microsoft.AspNetCore.Server.IISIntegration" Version="1.1.0" />
    <PackageReference Include="Microsoft.AspNetCore.Server.Kestrel" Version="1.1.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="1.1.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="1.1.0-preview4-final" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="1.1.0-preview4-final" />
    <PackageReference Include="Microsoft.Extensions.Configuration.EnvironmentVariables" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Configuration.Json" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Logging" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Logging.Console" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="1.1.0" />
    <PackageReference Include="Microsoft.Extensions.Options.ConfigurationExtensions" Version="1.1.0" />
    <PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL" Version="1.1.0" />
    <PackageReference Include="Npgsql.EntityFrameworkCore.PostgreSQL.Design" Version="1.1.0" />   </ItemGroup>

对于最新版本来说,工具似乎还不能很好地工作.例如,当我尝试运行dotnet ef它抱怨缺少project.json - 现在已经被删除了.

我正在使用Visual Studio 2017社区RC和集成的PM控制台可以运行添加迁移,更新数据库,...所以我不关心缺少dotnet ef支持,但如果你有任何解决方法的任何想法我会很感激因为我也喜欢使用VS Code代替Studio.

我的问题是现在我尝试构建一个ASP.Core MVC网站,大量使用标记帮助程序.但智能感知不适用于此:

VS2017有一个已知问题https://github.com/aspnet/Tooling/blob/master/known-issues-vs2017.md#tag-helpers-do-not-work,它链接到一个解决方法" 安装剃刀语言服务扩展 "

更新:

对于新版本Visual Studio 2017 Preview 15.3(从现在开始,我认为),razor language service当您选择ASP.NET and web development工作负载时,它被选为Visual Studio安装过程中的一个组件
