Question

我按照以下步骤使用模板创建了一个应用程序。

然后，右键单击References并选择Manage Nuget Packages...以更新所有依赖项：

恢复后，我成功构建了解决方案：

但是我无法创建新的控制器，我不知道错误来自哪里？

我确信在更新之前我可以使用这种方式创建新的控制器。更新后，它不是。

如何解决此问题？

我使用VS 2015和更新3。

更新2：

我已根据@ Tseng的评论更新了tools。但我仍然无法创建新的控制器：

它需要依赖：Microsoft.NetCore.App版本1.1.0。我试图添加，但它没有成功：

它说：Microsoft.NetCore.App不支持.Net Framework 4.6.1

现在我可以看到你的project.json，我看到了问题：你没有更新你的工具部分。

"tools": {
  "Microsoft.AspNetCore.Razor.Tools": "1.0.0-preview2-final",
  "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final",
  "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final",
  "Microsoft.Extensions.SecretManager.Tools": "1.0.0-preview2-final",
  "Microsoft.VisualStudio.Web.CodeGeneration.Tools": {
    "version": "1.0.0-preview2-final",
    "imports": [
      "portable-net45+win8"
    ]
  }

它仍然使用旧工具。

"tools": {
  "Microsoft.AspNetCore.Razor.Tools": "1.1.0-preview4-final",
  "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.1.0-preview4-final",
  "Microsoft.EntityFrameworkCore.Tools": "1.1.0-preview4-final",
  "Microsoft.Extensions.SecretManager.Tools": "1.1.0-preview4-final",
  "Microsoft.VisualStudio.Web.CodeGeneration.Tools": {
    "version": "1.1.0-preview4-final",
    "imports": [
      "portable-net45+win8"
    ]
  }

上次查看时，

1.1.0-preview4-final应该是正确的版本。同样适用于依赖项部分中的某些依赖项，例如Microsoft.EntityFrameworkCore.Tools，Microsoft.VisualStudio.Web.CodeGeneration.Tools，Microsoft.AspNetCore.Razor.Tools和Microsoft.VisualStudio.Web.CodeGenerators.Mvc

为什么我不应该更新asp.net核心中的所有依赖项？
