EF Core中使用事务和DbContext.SaveChanges方法（链接）

下面这篇微软官方文档，介绍了如何在EF Core中使用事务：

Using Transactions

注意文档中，这里有提到：

By default, if the database provider supports transactions, all changes in a single call to SaveChanges are applied in a transaction. If any of the changes fail, then the transaction is rolled back and none of the changes are applied to the database. This means that SaveChanges is guaranteed to either completely succeed, or leave the database unmodified if an error occurs.

也就是说DbContext.SaveChanges方法会将所有更改通过一个数据库事务来提交，这样就保证了所有更改要么全部提交成功，要么全部提交失败。

 

请注意，文档里面还提到了在.NET Core中TransactionScope对分布式事务的支持情况：Limitations of System.Transactions
