C# EF 6数据库。迁移不'；t在链接的项目中应用或查看新迁移
嘿，伙计们，这是我不久前的第一篇帖子 我最近遇到了一些我认为是bug或者我很愚蠢的问题。在过去的3个小时里，我一直在尝试为我的应用程序测试创建一个单独的testcontext，以便在构建之前测试我的应用程序数据库是否正常工作，这意味着我试图用种子testdata生成一个数据库，但我在测试数据库中实现迁移时遇到了困难 最奇怪的是，迁移历史记录表已经创建，但迁移中定义的表却没有。另外，当我在主应用程序上使用更新数据库注释时，一切都很好 这是我的测试：C# EF 6数据库。迁移不'；t在链接的项目中应用或查看新迁移,c#,asp.net-mvc,entity-framework,database-migration,C#,Asp.net Mvc,Entity Framework,Database Migration,嘿，伙计们，这是我不久前的第一篇帖子 我最近遇到了一些我认为是bug或者我很愚蠢的问题。在过去的3个小时里，我一直在尝试为我的应用程序测试创建一个单独的testcontext，以便在构建之前测试我的应用程序数据库是否正常工作，这意味着我试图用种子testdata生成一个数据库，但我在测试数据库中实现迁移时遇到了困难 最奇怪的是，迁移历史记录表已经创建，但迁移中定义的表却没有。另外，当我在主应用程序上使用更新数据库注释时，一切都很好 这是我的测试： [Fact] private a
