EF 6基于代码的迁移异常：Microsoft.VisualStudio.Data.Tools.Package不可序列化？ [英] EF 6 Code based migration exception: Microsoft.VisualStudio.Data.Tools.Package not serializable?

问题描述

我有这个配置

internal sealed class Configuration :DbMigrationsConfiguration<IAS.Models.ApplicationDbContext> {
            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我得到以下异常

when running upate-dataabase i get the following exception

推荐答案

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

Problem solved, i opened the file ..\packages\EntityFramework.6.0.0\tools\EntityFramework.psm and the line 611 states:

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

我检查我的解决方案后，我发现启动项目已经更改为数据库项目，更正了这一点，问题已经消失了。

I them after review my solution I found that the startup project was changed to the Database project, corrected this and the problem was gone.
