## v0.3.22

Browse Source 
- 优化 导航属性 ManyToOne 名称查找规则；
- 增加 IFreeSql.Aop 属性，未来所有拦截方法都在这里，第一期支持如下：
  * 监控 ToList 返回的的数据，用于拦截重新装饰；
  * 监视 Where，包括 select/update/delete，返回值 true 时可使上层不被执行；
  * 可自定义解析表达式；
- 增加 ISelect.TractToList，用于单次跟踪或审核实体；
- 优化 FreeSql.DbContext SaveChanges；

# 实体
FreeSql 使用模型执行数据访问，模型由实体类表示数据库表或视图，用于查询和保存数据。
可从现有数据库生成实体模型，提供 IDbFirst 生成实体模型。
或者手动创建模型，基于模型创建或修改数据库，提供 ICodeFirst 同步结构的 API（甚至可以做到开发阶段自动同步）。

# Performance
FreeSql Query & Dapper Query
```shell

测试方法：运行两次，以第二次性能报告，避免了首个运行慢不公平的情况。[查看测试代码](FreeSql.Tests.PerformanceTests/MySqlAdoTest.cs)
[Test code](FreeSql.Tests.PerformanceTests/MySqlAdoTest.cs)
FreeSql 目前使用的ExpressionTree+缓存，因为支持更为复杂的数据类型，所以比 Dapper Emit 慢少许。
