无法加载文件或程序集“Microsoft.SqlServer.Server”

sql

我正在尝试使用 Dapper 在我的 sqlserver 数据库中进行简单的插入。这是我的代码:

        using var db = DbContext.CreateConnection();
        db.Open();
        string sqlQuery =
            "INSERT INTO Account (Id, Balance, NumberOfTransactions) VALUES(@Id, @Balance, @NumberOfTransactions)";
        int rowsAffected = db.Execute(sqlQuery, entity);
        return rowsAffected > 0;

这是我的 DapperContext。

public DapperContext(IConfiguration configuration)
{
    _configuration = configuration;
    _connectionString = _configuration.GetConnectionString("DapperConnection");
}

public IDbConnection CreateConnection()
    => new SqlConnection(_connectionString);

但是当我到达这Execute条线时,我得到了无法加载文件或程序集“Microsoft.SqlServer.Server”。我不知道为什么。我的 SQLServer 由 docker 映像托管。而且我已经安装了服务器 nuget。这是我目前已安装的 nugets 列表:

    <PackageReference Include="Akka" Version="1.4.39" />
    <PackageReference Include="Akka.DependencyInjection" Version="1.4.39" />
    <PackageReference Include="Akka.Remote" Version="1.4.39" />
    <PackageReference Include="Dapper" Version="2.0.123" />
    <PackageReference Include="Dapper.EntityFramework" Version="2.0.90" />
    <PackageReference Include="Microsoft.Data.SqlClient" Version="5.0.0-preview3.22168.1" />
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="7.0.0-preview.5.22302.2" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="7.0.0-preview.5.22302.2">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="7.0.0-preview.5.22302.2" />
    <PackageReference Include="Microsoft.SqlServer.Server" Version="1.0.0" />
    <PackageReference Include="Microsoft.SqlServer.Types" Version="160.600.9-ctp2p0" />
    <PackageReference Include="Swashbuckle.AspNetCore" Version="6.2.3" />

任何人都可以帮助我这里可能出了什么问题,为什么我不断收到无法加载错误?我什至已经从Microsoft下载了 SQL Server,但我的想法是改用我的 docker 容器。

堆栈跟踪:

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.SqlServer.Server, Version=5.0.0.0, Culture=neutral, PublicKeyToken=23ec7fc2d6eaa4a5'. The system cannot find the file specified.
File name: 'Microsoft.SqlServer.Server, Version=5.0.0.0, Culture=neutral, PublicKeyToken=23ec7fc2d6eaa4a5'

我使用了错误版本的 nuget 包。我不得不替换PackageReference Include="Microsoft.Data.SqlClient" Version="5.0.0-preview3.22168.1PackageReference Include="System.Data.SqlClient" Version="4.8.3"并且它立即起作用
