## v0.9.16

Browse Source 
- 增加 BaseRepository.AttachOnlyPrimary 方法，只附加实体的主键值；
> 在更新前使用可实现不查询数据库再更新、也可以实现更新时不更新值为 null 的字段
```csharp
class T {
    public int id { get; set; }
    public string name { get; set; }
    public string other { get; set; }
}
var item = new T { id = 1, name = "xx" };
fsql.GetRepository<T>().AttachOnlyPrimary(item).Update(item); //只更新 name
```
- 修复 Lambda 表达式中 DateTime.Now.ToString("yyyyMMdd") 不能直接执行的 bug；
