Azure 上的新 Serenity 部署失败，对象名称“语言”无效答案

【问题标题】：New Serenity deployment failing on Azure with Invalid object name 'Languages'Azure 上的新 Serenity 部署失败，对象名称“语言”无效
【发布时间】：2021-06-25 11:22:24
【问题描述】：

使用 Serenity 框架 v 5.0.24。我有一个新的解决方案，其中包含一个小型演示，所有内容都可以在本地运行，但是当我尝试将其部署到 Azure 资源时，它似乎甚至无法创建数据库，但我不知道为什么。 “语言”是初始迁移单元中的第二件事，所以我假设它。我之前在以前的版本上部署了几十个宁静应用程序，所以我不是新手。这是原始异常输出：

【问题讨论】：

数据库如何安装在服务器上？位置或凭据可能不正确。这是您第一次在 Window 10 机器上安装吗？您是第一次使用 Core 安装吗？这次与以往有什么不同？
它已部署到 Azure 上的 WebApp 资源，这很好，因为它正在运行。该数据库也是 Azure 上的 SQLServer。我可以登录数据库。我无法确定与我之前执行此操作的时间有何不同。我已尝试删除所有资源并再次添加。如果凭据错误，我会收到一个特定错误告诉我。如果防火墙错误，我会收到有关它的特定错误。我只是从未见过在 Serenity 部署中发生这种情况，因为它们通常是无缝的。
您有前端（客户端到服务器）和后端（服务器到数据库）。当您过去遇到错误时，它们是后端的前端吗？当您运行 SSMS 时，您是否在服务器上运行？当您过去遇到错误时，您是否在 VS 中运行。 VS 不会自动以管理员身份运行。您需要右键单击 VS 快捷方式并选择以管理员身份运行。这看起来像是一个凭证问题，不确定问题发生在前/后的哪个位置。
感谢您的意见，但这都是 Azure 云中的东西，没有管理员或凭据问题。我现在已经用实际的分辨率回答了我自己的问题。
我让你“跳出框框思考”。您只是查看错误并没有记住迁移安全检查。

【解决方案1】：

为了他人的利益，我发现了自己的问题。我忽略了在第 203 行附近的 DataMigrations.cs 中删除了迁移安全检查，这部分会阻止您随意编写新数据库。我记得（也许）过去应用程序会警告您已跳过迁移，而不仅仅是在未找到的第一个 SQL 对象上拉异常。轻松搞定，就是觉得有点傻！
