…ceptions Fixed GetValidFileStreamOrDefault to return null instead of throwing InvalidOperationException when file size is not aligned to element size. This ensures ReadFirstOrDefault and ReadLastOrDefault methods follow the OrDefault convention of returning default values in unexpected cases rather than throwing exceptions. Added comprehensive tests to verify the correct behavior for misaligned files. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Summary
GetValidFileStreamOrDefaultmethod inFileHelpers.csto returnnullinstead of throwingInvalidOperationExceptionwhen file size is not aligned to element sizeReadFirstOrDefault<T>andReadLastOrDefault<T>methods follow the OrDefault convention of returning default values in unexpected casesProblem
The issue was in the
GetValidFileStreamOrDefaultmethod at lines 86-89, where anInvalidOperationExceptionwas thrown when the file size was not aligned to the element size. This violated the OrDefault convention where methods ending withOrDefaultshould return default values instead of throwing exceptions.Solution
Changed the exception-throwing code to return
null, which causes the calling OrDefault methods to return their default values as expected.Test Plan
