## Usage
|
## Usage
|
||||||
|
|
||||||
### Transaction ownership and failures
|
|
||||||
|
|
||||||
Both `ExecuteInTransactionAsync` overloads create, commit, and dispose a transaction when no transaction is already cached by the unit of work. After disposal, the cached reference is cleared, so a later call starts a fresh transaction.
|
|
||||||
|
|
||||||
If the action or commit fails, the owned transaction is rolled back. If rollback also fails (including when the provider reports a completed transaction), an `AggregateException` contains the original failure first and the rollback failure second. Disposal still runs.
|
|
||||||
|
|
||||||
When `BeginTransactionAsync` has already supplied a transaction to the caller, `ExecuteInTransactionAsync` runs the action inside that transaction and leaves commit, rollback, and disposal to the caller. Its cached reference is retained as before; the automatic cleanup above applies only to transactions owned by `ExecuteInTransactionAsync`.
|
|
||||||
|
|
||||||
Run the regression suite with `dotnet test hrynco-ef.slnx`.
