我有不同的DbContext连接到不同的数据库。添加迁移时,我的前两个DbContext工作正常,但添加的最后一个DbContext(FinalPmisDbContext)无法添加迁移。我已经在PM中尝试了这两个命令
Enable-Migrations -ContextTypeName SosaPmisApi.Models.FinalPmisDbContext -Force
这是我得到的结果:
Checking if the context targets an existing database...
Code First Migrations enabled for project SosaPmisApi.
然后我运行以下命令:
add-migration -ConfigurationTypeName SosaPmisApi.Migrations.FinalPmisDbContext.Configuration "AddedPropertySoa"
但是我得到这个错误:
迁移配置类型'SosaPmisApi.Migrations.FinalPmisDbContext.Configuration' was not be found in the assembly 'SosaPmisApi'.
这是我的DbContext:
using SosaPmisApi.Models.FinalCurtain;
using System.Data.Entity;
namespace SosaPmisApi.Models
{
public class FinalPmisDbContext : DbContext
{
public FinalPmisDbContext() : base("RevisionConnection") { }
public DbSet<PropertySoaDates> PropertySoaDates { get; set; }
}
}
编辑 我可以看到具有此功能的Configuration.cs。
namespace SosaPmisApi.Migrations
{
using System;
using System.Data.Entity;
using System.Data.Entity.Migrations;
using System.Linq;
internal sealed class Configuration : DbMigrationsConfiguration<SosaPmisApi.Models.FinalPmisDbContext>
{
public Configuration()
{
AutomaticMigrationsEnabled = false;
}
protected override void Seed(SosaPmisApi.Models.FinalPmisDbContext context)
{
// This method will be called after migrating to the latest version.
// You can use the DbSet<T>.AddOrUpdate() helper extension method
// to avoid creating duplicate seed data. E.g.
//
// context.People.AddOrUpdate(
// p => p.FullName,
// new Person { FullName = "Andrew Peters" },
// new Person { FullName = "Brice Lambson" },
// new Person { FullName = "Rowan Miller" }
// );
//
}
}
}
