entity-framework - Service Fabric 和 Entity Framework 迁移

Question

我将 Service Fabric 与 Entity Framework 6.1.3 结合使用。当我尝试使用“Enable-Migrations”启用迁移时出现错误:

Exception calling "SetData" with "2" argument(s): "Type 'Microsoft.VisualStudio.ProjectSystem.VS.Implementation.Package.Automation.OAProject' in assembly

我想 EF 找不到连接字符串，因为起始项目是一个 Service Fabric 应用程序(所以没有 web.config，而是一个 ApplicationManifest.xml 和多个环境配置)

有什么线索吗？ 谢谢， 阿尔贝托

您可以将连接字符串存储在 Azure 的 KeyVault 中，然后从那里提取您的基础设施项目。
