此套件包含 Microsoft.EntityFrameworkCore.SqlServer.Abstractions 和Microsoft.SqlServer.Types 這些可轉移的相依性,因此通常是唯一必需的套件。 安裝套件之後,您可以在應用程式呼叫 UseSqlServer 的過程中呼叫 UseHierarchyId,藉此使用 HierarchyId。 例如:C# 複製 options.UseSqlServer( connectionString, x => x.Use...
PMC 和 .NET CLI 命令都有兩個必要自變數:資料庫 連接字串,以及要使用的 EF Core 資料庫提供者。 Connection string 警告 本文使用本機資料庫,其不需要使用者進行驗證。 實際執行應用程式應該使用可用的最安全驗證流程。 如需已部署測試與實際執行應用程式驗證的詳細資訊,請參閱安全驗證流程。
反向工程是基于数据库架构的基架实体类型类和DbContext类的过程。 可使用 EF Core 包管理器控制台 (PMC) 工具的Scaffold-DbContext命令或 .NET 命令行接口 (CLI) 工具的dotnet ef dbcontext scaffold命令执行这一过程。 备注 此处所述的DbContext和实体类型的基架与使用 Visual Studio 的ASP.NET Core 中控制器的...
