Question

Is there an equivalent to TransactionScope that you can use with Azure Table Storage?

what I’m trying to do is the following:

using (TransactionScope scope = new TransactionScope) {
    account.balance -= 10;
    purchaseOrders.Add(order);
    accountDataSource.SaveChanges();
    purchaseOrdersDataSource.SaveChanges();
    scope.Complete();
}

If for some reason saving the account works, but saving the purchase order fails, I don’t want the account to decrement the balance.

Within a single table and single partition, you may write multiple rows in an entity group transaction. There’s no built-in transaction mechanism when crossing partitions or tables.

that said: remember that tables are schema-less, so if you really needed a transaction, you could store both your account row and your purchase order row in the same table, same partition, and do a single (transactional) save.
