+# 事务建议
+
+由于 AsyncLocal 平台兼容不好，所以交给外部管理。
+
+```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 ...
+    }
+    finally
+    {
+        _asyncUow.Value = null;
+    }
+    
+    uow.Commit();
+}
+```
