Question

我需要创建一个已加载数据的数据库。它没有返回任何错误，只是没有workinkg。数据库创建完美但空洞。我认为问题出在appConfig

中

上下文：

namespace Domain.DAL
{
    public class LandingContext : DbContext
    {
        public LandingContext() : base(Properties.Settings.Default.ConString)
        {
        Database.SetInitializer<LandingContext>(new CreateDatabaseIfNotExists<LandingContext>());
        Database.Initialize(true);
        }

    public DbSet<Package> Packages { get; set; }
    public DbSet<AbsProduct> Products { get; set; }

   }
}

初始化器：

namespace Domain.DAL
{
    public class LandingInitializer : CreateDatabaseIfNotExists<LandingContext>
    {
        protected override void Seed(LandingContext context)
        {
            Car kangoo = new Car(100, 2, "kangoo");
            context.Products.Add(kangoo);
            context.SaveChanges();

            base.Seed(context);
        }

    }
}

appconfig：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>
  <connectionStrings>
    <add name="Domain.Properties.Settings.ConString" connectionString="Data Source=ENZO-PC;Initial Catalog=GLB-Landing;Integrated Security=True" providerName="System.Data.SqlClient" />
  </connectionStrings>

  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="mssqllocaldb" />
      </parameters>
    </defaultConnectionFactory>
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>
  <contexts>
    <context type=" DAL.LandingContext, Domain">
      <databaseInitializer type="DAL.LandingInitializer, Domain" />
    </context>
  </contexts>
</configuration>

我重新放置

    Database.SetInitializer<LandingContext>(new CreateDatabaseIfNotExists<LandingContext>());

for：

    Database.SetInitializer<LandingContext>(new LandingInitializer());

工作......

数据库初始化程序不起作用
