AWS code-library documentation change
Summary
Updated .NET SDK version from v3 to v4, added XML documentation comments, improved error handling with try-catch blocks, and fixed null reference checks in pagination logic
Security assessment
The changes focus on code quality improvements (error handling, documentation) and SDK version updates. While added exception handling improves reliability, there's no evidence of addressing specific security vulnerabilities. The null-check for LastEvaluatedKey prevents runtime errors but doesn't mitigate security risks.
