I have encountered an issue that if a file is created before a transaction completed, it is visible and other process can still pick it up. E.g.

Class 1: write file and add a product to database.
IFileManager fileMgr = new TxFileManager();
using (var scope = new TransactionScope())
{
fileMgr.WriteAllText(path, contents); // File is visible instantly here, right?
db.AddProduct(product);
scope.Complete();
}

Class 2: a poller runs as a background thread to pickup the file for other process in a period of time.
poller.PickUpTheFile(path);

A problem is, Class 2 should not pickup the file when the transaction is not completed. I guess TXFileManager should have saved the file in a temporary folder before complete a transaction, correct?

Thank you anh,

That’s currently not supported by this framework. In theory, it can be done by implementing a separate transaction manager which is aware of the state of various transactions and can roll back incomplete transactions like the one in your example.
