Entity framework 为什么我的所有模型类都会添加到我'；m使用多个数据上下文类？

具有多个数据上下文的Entity Framework 6代码优先迁移

注意：这是我关于堆栈溢出的第一篇文章，如果我需要提供更多细节，请告诉我

仅供参考：我已经阅读了以下文章：

我也在尝试做类似的事情。我的问题围绕Configuration.cs文件中生成的CreateTable方法展开

我有29个模型类，我正在尝试设置4个不同的数据上下文

在我的第一个数据上下文RulingRequestContext中，我有29个模型类中的11个：

public class RulingRequestContext : BaseContext<RulingRequestContext>
{
    public DbSet<RulingRequest> RulingRequests { get; set; }
    public DbSet<Agency> Agencies { get; set; }
    public DbSet<RulingRequestGroup> RulingRequestGroups { get; set; }
    public DbSet<RulingRequestOverallOutcome> RulingRequestOverallOutcomes { get; set; }
    public DbSet<RulingRequestType> RulingRequestTypes { get; set; }
    public DbSet<RulingRequestResult> RulingRequestResults { get; set; }
    public DbSet<Issue> Issues { get; set; }
    public DbSet<Decision> Decisions { get; set; }
    public DbSet<RulingRequestRoutingInformation> RulingRequestRoutingInformations { get; set; }
    public DbSet<Staff> Staffs { get; set; }
    public DbSet<StatusOfRulingRequest> StatusOfRulingRequests { get; set; }

问题:

（1） 是否所有29个模型类都因为关系/虚拟属性而添加到RulingRequest的Configuration.cs？例如，由于我的所有4个数据上下文类都有：public virtual Agency{get；set；}，所有这些模型类都被添加到我的RulingRequestContext.cs类的Configuration.cs文件中

（2） 假设我的初始数据上下文类（RulingRequestContext）及其Configuration.cs类按预期工作，我是否应该注释掉其他3个Configuration.cs类中的所有CreateTable代码

（3） 或者我应该注释掉RulingRequestContext中未显示为DBSet属性的所有模型类的CreateTable代码吗？然后对我的其他3个DataContext类执行相同的操作

谢谢你花时间阅读这篇文章！请让我知道，如果有什么我可以做或不做，使我的职位在未来更好

是的，它正在抓取相关实体。您的链接谈到从其他上下文中注释掉表“在运行update命令之前，注释掉为Users表生成的代码，如上所示。因为Users表已经由第一次DbContext迁移创建。”

(1) enable-migrations -ContextTypeName <DbContext-Name-with-Namespaces> -MigrationsDirectory:<Migrations-Directory-Name>
(2) Add-Migration -configuration <DbContext-Migrations-Configuration-Class-with-Namespaces> <Migrations-Name>
(3) Update-Database -configuration <DbContext-Migrations-Configuration-Class-with-Namespaces> -Verbose
