C# Azure管道-x27；类型或命名空间名称'；基础设施'；命名空间中不存在'；

我知道这个问题已经有无数人问了。然而，我没有找到任何有效的解决方案

我有一个.NET网站项目，我正在使用EntityFramework6。 在当地，该项目没有问题，一切正常。但当我将其推送到GitHub上的主分支，以便将其部署到我的Azure网站时，会显示以下消息：

这是我的yml文件：

    on:
  push:
    branches:
      - master
  workflow_dispatch:

jobs:
  build-and-deploy:
    runs-on: windows-latest

    steps:
    - uses: actions/checkout@master

    - name: Set up .NET Core
      uses: actions/setup-dotnet@v1
      with:
        dotnet-version: '3.1.301'

    - name: Restore NuGet packages
      run: nuget restore MyOnlineCV.sln

    - name: Build with dotnet
      run: dotnet build --configuration Release

    - name: dotnet publish
      run: dotnet publish -c Release -o ${{env.DOTNET_ROOT}}/myapp

它发生在“使用dotnet构建”步骤上。我该怎么解决呢？ 提前谢谢你

还有我的.csproj给那些好奇的人：

6.2.0

这个构建有时已经工作了，但是一推它就停止工作了。我没有更改任何后端文件。我迷路了

编辑 以下是project packages.config：

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="6.4.4" targetFramework="net472" />
  <package id="EntityFramework.fr" version="6.2.0" targetFramework="net472" />
</packages>

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="6.4.4" targetFramework="net472" />
</packages>

您在这里使用4.7.2框架构建项目，但在yml中您引用的是.Net核心框架。这可能是问题所在吗？

最后，为了解决问题，我做了以下操作： 我卸载了每个实体框架nuget。 我删除了packages.config，并在.csproj中删除了以下内容：

<ItemGroup>
    <PackageReference Include="EntityFramework">
       <Version>6.4.4</Version>
    </PackageReference>
    <PackageReference Include="EntityFramework.fr">
      <Version>6.2.0</Version>
    </PackageReference>
</ItemGroup>

6.4.4
6.2.0

我重新安装了Entity Framework，下面是新的packages.config：

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="6.4.4" targetFramework="net472" />
  <package id="EntityFramework.fr" version="6.2.0" targetFramework="net472" />
</packages>

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="6.4.4" targetFramework="net472" />
</packages>

以及.csproj文件中添加的行：

<Import Project="..\packages\EntityFramework.6.4.4\build\EntityFramework.props" Condition="Exists('..\packages\EntityFramework.6.4.4\build\EntityFramework.props')" />
...
<None Include="packages.config" />
...
<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
      <ErrorText>This project is referencing to missing NuGet packages on this computer. Use the NuGet packages restoration option to download them. For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is: {0}.</ErrorText>
    </PropertyGroup>
    <Error Condition="!Exists('..\packages\EntityFramework.6.4.4\build\EntityFramework.props')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\EntityFramework.6.4.4\build\EntityFramework.props'))" />
    <Error Condition="!Exists('..\packages\EntityFramework.6.4.4\build\EntityFramework.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\EntityFramework.6.4.4\build\EntityFramework.targets'))" />
  </Target>
  <Import Project="..\packages\EntityFramework.6.4.4\build\EntityFramework.targets" Condition="Exists('..\packages\EntityFramework.6.4.4\build\EntityFramework.targets')" />

...
...
此项目正在引用此计算机上缺少的NuGet程序包。使用NuGet软件包还原选项下载它们。有关详细信息，请参阅http://go.microsoft.com/fwlink/?LinkID=322105. 缺少的文件是：{0}。

然后我承诺使用git，管道工作正常

---

请注意，管道中的步骤

run:nuget restore MyOnlineCV.sln

非常重要。如果没有它，就会出现错误。

您可以为您的项目/解决方案显示

packages.config

吗？我添加了file@Dyanek您是否看到在

Restore numget packages

步骤中还原的包？您是否尝试过删除

packages.config

文件并重新创建它？看起来你在使用GitHub操作，而不是Azure管道进行构建。我不这么认为。事实上，我的解决方案的主要项目是使用.Net核心框架。EF6的第二个项目使用4.7.2框架
