我想发布项目时无法恢复 csproj 文件

Question

我正在尝试制作 C# 代码的 exe 文件，我使用此设置在一个文件中创建它。但是，它在恢复 csproj 时失败并且 return 此错误消息：

Build started...
1>------ Build started: Project: Email-gen, Configuration: Release Any CPU ------
1>Email-gen -> C:\Users\Mohammed\source\repos\Email-gen\Email-gen\bin\Release\net6.0\Email-gen.dll
2>------ Publish started: Project: Email-gen, Configuration: Release Any CPU ------
2>Determining projects to restore...

========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
========== Publish: 0 succeeded, 1 failed, 0 skipped ==========

此 csproj 文件：

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <RootNamespace>Email_gen</RootNamespace>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

</Project>

这是发布者的设置

Answer 1

请确保已启用 Nuget 基本源，因为根据您的日志，它仅离线搜索包。

Visual Studio 菜单： Tools => Options => Package sources => 启用 nuget.org

此外，要使您的项目独立于 VS 设置，可以将其添加到 .csproj:

   <RestoreAdditionalProjectSources>
      https://api.nuget.org/v3/index.json
    </RestoreAdditionalProjectSources>

P.S。我在标签中看到 Visual studio 2017，但您只能使用 2022 一个来构建 .NET 6 应用程序
