更新到新包Microsoft.EntityFrameworkCore.SqlServer 1.1.2后,我尝试创建DBContext时出错:

System.IO.FileLoadException发生HResult = 0x80131040
Message =无法加载文件或程序集'Microsoft.Extensions.DependencyInjection.Abstractions,Version = 1.1.0.0,Culture = neutral,PublicKeyToken = adb9793829ddae60'或其依赖项之一.定位的程序集的清单定义与程序集引用不匹配.(来自HRESULT的异常:0x80131040)Source = Microsoft.EntityFrameworkCore StackTrace:位于C:\ src\backend \中Services.Infrastructure.Data.SqlServerDbContext..ctor(DatabaseOptions databaseOptions)的Microsoft.EntityFrameworkCore.DbContext..ctor(DbContextOptions选项) Packages\Services.Infrastructure\Data\SqlServerDbContext.cs:位于C:\ src\backend\Modules\Translations\Translations.Api\Data\TranslationsDbContext.cs中Translations.Api.Data.TranslationsDbContext..ctor(DatabaseOptions databaseOptions)的第16行:第16行

我的基础DbContext

public class SqlServerDbContext : DbContext
{
    private readonly DatabaseOptions _databaseOptions;

    protected SqlServerDbContext(DatabaseOptions databaseOptions)
    {
        if (string.IsNullOrEmpty(databaseOptions.ConnectionString))
            throw new Exception("Database connection string is missed.");

        _databaseOptions = databaseOptions;
    }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlServer(_databaseOptions.ConnectionString);
    }
}

我使用的数据库选项

public class DatabaseOptions
{
    public string ConnectionString { get; set; }
}

我创建上下文实例的地方

 var dbOptions = new DatabaseOptions { ConnectionString …
