 * Fix tuple/multi-value projections in queries to use Queryable.Select instead of Enumerable.Select when the source is IQueryable, preserving query composition and enabling async operations like ToListAsync() in Entity Framework Core. ([Issue #3782](https://github.com/dotnet/fsharp/issues/3782), [Issue #15133](https://github.com/dotnet/fsharp/issues/15133))
 * Fix EvaluateQuotation to handle Sequential expressions, void method calls (unit return), and other patterns that were previously throwing NotSupportedException. Also properly handles unit-returning expressions by using Action delegates instead of Func delegates. ([Issue #19099](https://github.com/dotnet/fsharp/issues/19099))
 * Fix query conditionals without else branch (if-then only) that were causing type mismatch errors. Now properly extracts element type from IQueryable for creating empty sequences. ([Issue #3445](https://github.com/dotnet/fsharp/issues/3445))
+* Ensure culture-independent parsing of .NET-style interpolated string holes. ([Issue #19367](https://github.com/dotnet/fsharp/issues/19367), [PR #19370](https://github.com/dotnet/fsharp/pull/19370))
