DirectoryCatalog should not do ToUpper if case sensitivity is enabled #111181
Description
Description
This method will call ToUpperInvariant on the file paths for Windows. This causes issues if case-sensitivity has been enabled for a directory. The check where we return early should likely be updated to account for whether the directory has case-sensitivity enabled.
Reproduction Steps

Expected behavior

Actual behavior
File paths do not respect case-sensitivity.
