AWS code-library documentation change

Service: code-library · 2026-01-10 · Documentation low

File: code-library/latest/ug/cloudformation_code_examples.md

Summary

Removed the .NET SDK code example for getting started with CloudFormation, including the note about GitHub examples and the entire HelloCloudFormation implementation.

Security assessment

The change removes a general-purpose code example without any security context. The removed content included error handling for credential issues (like SSO setup), but this is standard authentication guidance, not evidence of addressing a specific vulnerability. No security advisories, vulnerability fixes, or security enhancements are referenced in the change.
