dotnet core user-secrets 可执行文件神秘丢失，为什么？

Question

安装了最新的（我认为）.NET Core，通过 Visual Studio 2015 创建了一个 .NET Core Web 项目，并尝试开始使用用户机密。 CLI声称它丢失了（声称已经安装了它......），如下：

E:\Projects\CodeServer>dotnet --version
1.0.0-preview1-002702

E:\Projects\CodeServer>dotnet restore
 <snip>
log  : Restoring packages for tool 'Microsoft.Extensions.SecretManager.Tools' in E:\Projects\CodeServer\src\CodeServer\project.json...
 <snip>
log  : Restore completed in 2345ms.

NuGet Config files used:
    C:\Users\Work User\AppData\Roaming\NuGet\NuGet.Config
    C:\ProgramData\nuget\Config\Microsoft.VisualStudio.Offline.config

Feeds used:
    https://api.nuget.org/v3/index.json
    C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\

E:\Projects\CodeServer>dotnet user-secrets -h
No executable found matching command "dotnet-user-secrets"

E:\Projects\CodeServer>

同时为每个请求添加 project.json 文件：

Answer 1

使用 project.json 文件的 tools 部分中定义的任何工具包时，必须从包含 project.json 文件的同一目录中使用它们。

例如，您的 project.json 文件在 E:\Projects\CodeServer\src\CodeServer\project.json 中，但您正试图执行来自 E:\Projects\CodeServer 的命令。如果您在尝试使用这些工具之前切换到 E:\Projects\CodeServer\src\CodeServer\ 目录，这些命令将起作用。

Answer 2

我发现包管理器控制台有时（或一直）无法使用正确的目录（即使在默认项目下拉列表中选择了它）。如果您首先执行命令 'cd src\YourProjectName' 然后例如'dotnet user-secrets -h'（寻求帮助）您应该能够使用用户机密工具。

Answer 3

该问题的公认答案是正确的，但 project.JSON 文件已不存在。（Visual Studios 2017 和 .Net Core 2.1）它已被替换为 "your-app-name".csproj 文件。参考：
