AWS code-library documentation change

Service: code-library · 2025-07-01 · Documentation low

File: code-library/latest/ug/csharp_3_ec2_code_examples.md

Summary

Removed 'Get started' section containing C# code example for EC2 DescribeSecurityGroups operation

Security assessment

The change deletes a security group listing example but shows no evidence of addressing security vulnerabilities. While security groups are security-related infrastructure, the documentation change itself doesn't indicate any security fixes or new security guidance.
