C# MSBUILD:错误MSB1003:指定项目或解决方案文件

我试图在键入时构建的示例应用程序的说明

dotnet restore 

在命令行

dotnet --version 

报告

2.1.300

当我这样做时，我得到以下错误

MSBUILD : error MSB1003: Specify a project or solution file.
The current working directory does not contain a project or solution file.

我正在执行命令的文件夹包含.cs文件，但不包含.sln或.csproj文件

.NetCore是否需要.csproj文件

代码来自对的回答，但github项目已被删除

我确实尝试创建了一个.csproj文件，但我很难猜到要放入哪些包

[更新]

我添加了以下.csproj文件

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.1</TargetFramework>
  </PropertyGroup>

</Project>

我知道如何使用package manager，但我如何找到所有内容的正确版本

工具->Nuget软件包管理器->管理解决方案的软件包报告错误

Microsoft Visual Studio
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

[更新]

我保存了所有内容，关闭了.sln文件并重新打开。然后我进入了Nuget软件包管理器

[更新]

我已经安装了Microsoft.Azure.KeyVault（3.0.0）和Newtonsoft.Json（11.0.2） 我在Microsoft.IdentityModel.Clients.ActiveDirectory中遇到问题 当我尝试Microsoft.IdentityModel时，它是错误的框架

Package 'Microsoft.IdentityModel 6.1.7600.16394' was restored using ''.NETFramework, Version=v4.61'
instead of the projecttargetframework '.NETCoreApp,Version=v2.1' 
This package may not be fully compatible with your project

[更新] 谷歌搜索“使用Microsoft.IdentityModel.Clients.ActiveDirectory核心”

发现 并在下午跑步

Install-Package Microsoft.IdentityModel.Clients.ActiveDirectory -Version 3.19.8

[更新] 尝试使用语句搜索Bouncy Castle并找到

Install-Package BouncyCastle.NetCore -Version 1.8.2

[更新]

重建全部成功，现在我在的第47行有一个运行时错误

var waitHandle=keyVaultObj.CreateSecretKeyValuePair（VaultName）

---

发生错误是因为我没有.csproj文件，作者没有将其包含在源代码中。

该问题记录了我构建过程中的步骤。

当前工作目录是否包含项目或解决方案文件？从哪个目录运行此命令？谢谢，我更新了该问题。我收到的代码中没有.csproj或.sln文件，因此需要先修复它…您是如何创建此项目的？请与我们分享有关您的项目结构的屏幕截图。您应该将问题和答案分开，并将答案部分放在此处：）
