# RoomSharp 0.5.3 - Release Notes

## Highlights

- Source generator hardening for `[Transaction]`, query parameter rewriting, and entity resolution.
- Safer generated SQL preparation for provider-specific syntax.
- Additional tests for generator correctness and SQL scanning edge cases.

## Source Generator

- `[Transaction]` on streaming DAO methods now reports a compile-time diagnostic. `IAsyncEnumerable<T>` results execute over time, so a transaction wrapper around the method call cannot define a clear lifetime.
- Generated transaction wrappers pass the DAO `CancellationToken` into `RunInTransactionAsync` and `RunInTransaction`.
- Query parameter replacement is now SQL-aware. It does not rewrite:
  - PostgreSQL casts like `created_at::date`.
  - SQL Server variables like `@@ROWCOUNT`.
  - String literals.
  - SQL comments.
- Entity and view lookup now prefers fully-qualified type names before simple names.

## Runtime

- Added `SqlHelpers.ReplaceNamedParameters()` for safe generated query preparation.
- Improved consistency between SQL diagnostics and runtime SQL preparation for named parameters.

## Compatibility

No intentional breaking API changes.

<Note>
If you previously relied on `[Transaction]` with `IAsyncEnumerable<T>`, that combination now fails at build time. Use an explicit transaction/session scope around enumeration instead.
</Note>

## Verification

- Source generator tests cover transaction wrappers, transaction streaming diagnostics, safe parameter replacement, and fully-qualified entity selection.
- SQL scanner tests cover PostgreSQL casts and SQL Server system variables.
