从ASP.NET Core 1.0升级到1.1后，Tag Helper智能感应不起作用

Question

从ASP.NET Core 1.0 to 1.1升级后。但Tag Helper Intellisense不起作用。什么可能会丢失？：

project.json

{ 
    "userSecretsId": "aspnet-ABCTest-6af8ade3-87ff-4468-a9ce-8bb69c696ab8", 

    "dependencies": {

     "type": "platform" 
    }, 
    "Microsoft.EntityFrameworkCore.SqlServer": "1.1.0", 
    "Microsoft.EntityFrameworkCore.Tools": "1.1.0-preview4-final", 
    "Microsoft.AspNetCore.Mvc": "1.1.0",

    "Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore": "1.1.0", 
    "Microsoft.AspNetCore.Identity": "1.1.0",

    "Microsoft.AspNetCore.Razor.Tools": "1.1.0-preview4-final", 
    "Microsoft.AspNetCore.Server.IISIntegration": "1.1.0", 
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.1.0-preview4-final", 
    "Microsoft.AspNetCore.StaticFiles": "1.1.0", 
    "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.1.0", 
    "Microsoft.Extensions.Configuration.Json": "1.1.0", 
    "Microsoft.Extensions.Configuration.UserSecrets": "1.1.0", 
    "Microsoft.Extensions.Logging": "1.1.0", 
    "Microsoft.Extensions.Logging.Console": "1.1.0", 
    "Microsoft.Extensions.Logging.Debug": "1.1.0", 
    "Microsoft.Extensions.Options.ConfigurationExtensions": "1.1.0", 
    "Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.1.0", 
    "Microsoft.VisualStudio.Web.CodeGeneration.Tools": "1.1.0-preview4-final", 
    "Microsoft.VisualStudio.Web.CodeGenerators.Mvc": "1.1.0-preview4-final" }, 

    "tools": { 
    "BundlerMinifier.Core": "2.0.238" 
    }, 

    "frameworks": { 
    "netcoreapp1.1": { 
     "imports": [ 
     "dotnet5.6", 
     "portable-net45+win8" 
     ] 
    } 
    }, 

    "buildOptions": { 
    "emitEntryPoint": true, 
    "preserveCompilationContext": true 
    }, 

    "runtimeOptions": { 
    "configProperties": { 
     "System.GC.Server": true 
    } 
    }, 

    "publishOptions": { 
    "include": [ 
     "wwwroot", 
     "Views", 
     "Areas/**/Views", 
     "appsettings.json", 
     "web.config" 
    ] 
    }, 

    "scripts": { 
    "prepublish": [ "bower install", "dotnet bundle" ], 
    "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ] 
    } 
} 

UPDATE：

_ViewImports.cshtml：

@using myProj 
@using myProj.Models 
@using myProj.Models.AccountViewModels 
@using myProj.Models.ManageViewModels 
@using myProj.AspNetCore.Identity 
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers 

构建工作正常。标签辅助函数也工作，但我不得不硬编码的属性，如asp-controller，asp-action，asp-for，asp-items等。这是工作之前，我搬到了ASP.NET 1.1的核心

还有一张纸条就在包装前节Eric Anderson关于智能感知相关问题的文章here。不知道这是否与此有关。

Answer 1

问题与Microsoft.AspNetCore.Razor.Tools。

你拥有了它的相关性，但是你需要把它添加到工具也：

"tools": { 
    "BundlerMinifier.Core": "2.0.238", 
    "Microsoft.AspNetCore.Razor.Tools": "1.1.0-preview4-final" 
    }, 

Answer 2

这是我必须配置我project.json以获取标记辅助智能感知： 通知行注释掉他们的航班吗相当于未注释：

"dependencies": { 
    "Microsoft.AspNetCore.Diagnostics": "1.1.0", 
    "Microsoft.AspNetCore.Mvc": "1.1.0", 
    "Microsoft.AspNetCore.Mvc.Core": "1.1.0", 
    "Microsoft.AspNetCore.Mvc.TagHelpers": "1.1.0", 
    "Microsoft.AspNetCore.Razor": "1.1.0", 
    "Microsoft.AspNetCore.Razor.Design": "1.0.0-preview3-final", 
    //"Microsoft.AspNetCore.Razor.Design": "1.1.0-preview4-final", 
    "Microsoft.AspNetCore.Razor.Runtime": "1.1.0", 
    "Microsoft.AspNetCore.Razor.Tools": { 
     "version": "1.0.0-preview2-final", 
     //"version": "1.1.0-preview4-final", 
     "type": "build" 
    }, 
    "Microsoft.AspNetCore.Server.IISIntegration": "1.1.0", 
    "Microsoft.AspNetCore.Server.Kestrel": "1.1.0", 
    "Microsoft.AspNetCore.Session": "1.1.0", 
    "Microsoft.Extensions.Configuration.FileExtensions": "1.1.0", 
    "Microsoft.Extensions.Configuration.Json": "1.1.0", 
    "Microsoft.Extensions.Logging.Console": "1.1.0" 
}, 

"tools": { 
    "Microsoft.AspNetCore.Razor.Tools": "1.0.0-preview2-final" 
    //"Microsoft.AspNetCore.Razor.Tools": "1.1.0-preview4-final" 
}, 

所以，基本上，无论是* Razor.Design和* Razor.Tools不得不留在1.0.0-preview3决赛。

另请注意，正如@Alex所述，您还需要在“工具”中指定* .Razor.Tools。 我希望这可以帮助。这确实很糟糕。

忍者编辑：不要忘了建立你的项目，intellisense不会工作，直到你做。可能还必须关闭并重新打开这些文件。

Answer 3

在我的情况下，我有针对性net46，然后当我改变为net461，它再次工作。我也添加版本和导入到包部分。

"tools": { 
    "Microsoft.AspNetCore.Razor.Tools": { 
    "version": "1.1.0-preview4-final", 
    "imports": ["portable-net45+win8"] 
},

只是一个说明，上述问题直到我安装了Razor语言服务才解决了我的问题。现在一切正常。

不知道这是一个要求仍在，但我也安装了剃刀工具。 它安装了截至2017年5月1日的Preview4-final。
