Cleanup Issue-URLs in Code · Issue #63902 · dotnet/runtime identified a workaround in place and it's unclear if the backing issue that necessitated the workaround has been resolved.

• The original issue was: Add IsolatedStorageFile factory methods with Evidence dependencies · Issue #18208 · dotnet/runtime
• The PR that added the comment was: Use [MemberNotNull] to reduce use of = null!; by stephentoub · Pull Request #37490 · dotnet/runtime

The workaround should be evaluated to determine if it's still necessary. With the findings, we should either update the code to remove the workaround, or the code comment to reference an open issue for tracking when we can remove the workaround.
