使用实体框架还原数据库中的更改

Question

I am using SQL Server as my back end database and Entity Framework 6 to access it.

I want to undo all the changes done to the database by a method. The method makes several calls to 4 different databases and thus 4 different contexts. I am not able to keep track of changes to revert them at the end.

I am aware of context.ChangeTracker.Entries() that keeps record of DB changes. But I am unable to utilize it because changes are lost as soon as a context goes out of scope. And I need need to revert the changes at the end of methods after accessing all 4 databases.
