据我所知,我已经将相关的NuGet包添加到以下C#控制台项目中。但是,我无法使用相应的命名空间。

using Microsoft.EntityFrameworkCore.Migrations.Design;

注: 不要混淆 它与 Microsoft.EntityFrameworkCore.Design

错误:

Program.cs(2,48):[CS0234]类型或命名空间名称“Design” 命名空间“Microsoft”中不存在。EntityFrameworkCore。移民' (是否缺少程序集引用?)

已安装的nuget软件包列表:

<ItemGroup>
      <PackageReference Include="Microsoft.EntityFrameworkCore" Version="8.0.12" />
      <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="8.0.12">
        <PrivateAssets>all</PrivateAssets>
        <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      </PackageReference>
      <PackageReference Include="Microsoft.EntityFrameworkCore.Relational" Version="8.0.12" />
      <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="8.0.12" />
      <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="8.0.12">
        <PrivateAssets>all</PrivateAssets>
        <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      </PackageReference>
    </ItemGroup>

我错过了什么?

来自Documents\PACKAGE.md文档:

默认情况下,该软件包将安装 PrivateAssets="All" 所以工具组件不会包含在您发布的文档中应用程序。例如:

<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="8.0.2">
    <PrivateAssets>all</PrivateAssets>
    <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
</PackageReference>

如果你想在运行时使用它,请将包引用更改为以下内容:

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="9.0.1" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="9.0.1" />
  </ItemGroup>

</Project>
