+# 前言
+
+尝试过 ado.net、dapper、ef，以及Repository仓储，甚至自己还写过生成器工具，以便做常规CRUD操作。
+
+它们日常操作不方便之处：
+
+- 每次使用前需要声明，再操作；
+
+- 很多人一个实体类，对应一个操作类（或DAL、DbContext、Repository）；
+
+BaseEntity 是一种极简单的 CodeFirst 开发方式，特别对单表或多表CRUD，利用继承节省了每个实体类的重复属性（创建时间、ID等字段），软件删除等功能，进行 crud 操作时不必时常考虑仓储的使用；
+
+本文介绍 BaseEntity 一种极简约的 CRUD 操作方法。
+
+# 功能特点
+
+- 自动迁移实体结构（CodeFirst），到数据库；
+
+- 直接操作实体的方法，进行 CRUD 操作；
+
+- 简化用户定义实体类型，省去主键、常用字段的配置（如CreateTime、UpdateTime）；
+
+- 实现单表、多表查询的软删除逻辑；
+
+# 声明
+
+> dotnet add package FreeSql.Extensions.BaseEntity
+
+> dotnet add package FreeSql.Provider.Sqlite
+
+```csharp
+BaseEntity.Initialization(fsql, null);
+```
+
+1、定义一个主键 int 并且自增的实体类型，BaseEntity TKey 指定为 int/long 时，会认为主键是自增；
+
+```csharp
+public class UserGroup : BaseEntity<UserGroup, int>
+{
+    public string GroupName { get; set; }
+}
+```
+
+如果不想主键是自增键，可以重写属性：
+
+```csharp
+public class UserGroup : BaseEntity<UserGroup, int>
+{
+    [Column(IsIdentity = false)] 
+    public override int Id { get; set; }
+    public string GroupName { get; set; }
+}
+```
+> 有关更多实体的特性配置，请参考资料：https://github.com/2881099/FreeSql/wiki/%e5%ae%9e%e4%bd%93%e7%89%b9%e6%80%a7
+
+2、定义一个主键 Guid 的实体类型，保存数据时会自动产生有序不重复的 Guid 值（不用自己指定 Guid.NewGuid()）；
+
+```csharp
+public class User : BaseEntity<UserGroup, Guid>
+{
+    public string UserName { get; set; }
+}
+```
+
+# CRUD 使用
+
+```csharp
+//添加
+var item = new UserGroup { GroupName = "组一" };
+item.Insert();
+
+//更新
+item.GroupName = "组二";
+item.Update();
+
+//添加或更新
+item.Save();
+
+//软删除
+item.Delete();
+
+//恢复软删除
+item.Restore();
+
+//根据主键获取对象
+var item = UserGroup.Find(1);
+
+//查询数据
+var items = UserGroup.Where(a => a.Id > 10).ToList();
+```
+
+实体类型.Select 是一个查询对象，使用方法和 FreeSql.ISelect 一样；
+
+支持多表查询时，软删除条件会附加在每个表中；
+
+> 有关更多查询方法，请参考资料：https://github.com/2881099/FreeSql/wiki/%e6%9f%a5%e8%af%a2
+
+# 事务建议
+
+由于 AsyncLocal 平台兼容不好，所以交给外部管理事务。
+
+```csharp
+static AsyncLocal<IUnitOfWork> _asyncUow = new AsyncLocal<IUnitOfWork>();
+
+BaseEntity.Initialization(fsql, () => _asyncUow.Value);
+```
+
+在 Scoped 开始时： _asyncUow.Value = fsql.CreateUnitOfWork(); (也可以使用 UnitOfWorkManager 对象获取 uow)
+
+在 Scoped 结束时：_asyncUow.Value = null;
+
+如下：
+
+```csharp
+using (var uow = fsql.CreateUnitOfWork())
+{
+    _asyncUow.Value = uow;
+
+    try
+    {
+        //todo ... BaseEntity 内部 curd 方法保持使用 uow 事务
+    }
+    finally
+    {
+        _asyncUow.Value = null;
+    }
+    
+    uow.Commit();
+}
+```
