基于EF 6代码的迁移异常:Microsoft.VisualStudio.Data.Tools.Package不可序列化？

我有这个配置

internal sealed class Configuration :DbMigrationsConfiguration {
            public Configuration() {
                AutomaticMigrationsEnabled = false;
                ContextKey = "IAS.Models.ApplicationDbContext";
            }

            protected override void Seed( IAS.Models.ApplicationDbContext context ) {
                var baseDir = AppDomain.CurrentDomain.BaseDirectory;
                context.Database.ExecuteSqlCommand(File.ReadAllText(baseDir + "\\MyInsertScriptsql"));
        }
    }

当运行upate-dataabase时,我得到以下异常

E-Bat.. 6

问题解决了,我打开了文件..\packages\EntityFramework.6.0.0\tools\EntityFramework.psm和第611行:

 $domain.SetData('startUpProject', $startUpProject)

我查看了他的解决方案后,我发现启动项目已更改为数据库项目,更正了问题并且问题已经消失.
