Remarks
A Unit of Work tracks every change to every persistent object during a transaction that can affect a data store. Its CommitChangesAsync method commits all object changes to a data store.

Calling the CommitChangesAsync method automatically calls Session.CommitTransaction (in explicit units of work, ExplicitUnitOfWork.CommitTransaction is called).
Note
If a save operation fails (for example, due to a database constraint violation), the XPO can raise the following exceptions:
