Map VB.NET char comparison with an empty string to char.MinValue to match runtime behavior and prevent logic errors during compilation. Added a unit test. Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>
Map VB.NET char comparison with an empty string to char.MinValue to match runtime behavior and prevent logic errors during compilation. For `Option Compare Text`, map it appropriately using `Microsoft.VisualBasic.CompilerServices.Conversions.ToString` to prevent `char` being compared to an empty string. Added characterization tests.

…omparison fix Remove leftover patch artifacts (.orig, .rej, patch file) and temporary TestDotNet debugging files that were committed by mistake. Expand the regression test to also cover the not-equal (<>) operator case. https://claude.ai/code/session_01AkwUvu3XuCdj3D4axoX4UX

There was a problem hiding this comment.
Look like a hack to make the specific test case work rather than the general fix to the root cause
