AWS Upgrades .NET Modernization After Microsoft/GitHub Tooling Debut

Just days after Microsoft/GitHub announced AI-powered .NET app modernization, AWS announced an AI-powered .NET app modernization upgrade.

While Microsoft and GitHub use GitHub Copilot as the tool, and Azure was the cloud target, the scheme from Amazon Web Services is called AWS Transform for .NET.

It was today described as "an agentic AI service for modernizing .NET applications at scale" with new report capabilities. Just a couple days before, as sister pub Visual Studio Magazine reported, was the GA debut of new capabilities in Copilot tooling (see "Copilot Does Azure-Focused .NET App Modernizations in Visual Studio").

AI-Powered Modernization Workflow
AWS said Transform for .NET helps organizations assess, upgrade, and migrate legacy applications with minimal manual effort. The company describes it as providing "end-to-end migration" that spans assessment through deployment, with a goal to "simplify the migration journey with full visibility, control, and predictability, while delivering higher quality outcomes."

The service analyzes codebases, detects blockers, and applies guided fixes automatically. AWS explained that it "analyzes codebases, surfaces blockers, and suggests fixes--automating repetitive steps and reducing tech debt so developers can focus on higher value work." In practice, this means dependency updates, configuration changes, and security remediation can be handled in a loop that validates changes against existing tests and pipelines.

New Transformation Reports
The new reporting feature is designed to give organizations detailed visibility into modernization progress. AWS said every recommendation is reviewable, and now transformation reports provide breakdowns of what issues were found, how they were remediated, and what remains outstanding. The company explained: "Every recommendation is reviewable and every change is validated through your tests and pipelines. Built-in security checks catch CVEs (Common Vulnerabilities and Exposures) early, ensuring alignment with your standards and policies."

The reports aggregate results from assessment through deployment, summarizing code changes, dependency upgrades, and security actions taken. They also highlight blockers that require human intervention. AWS positions the reports as a way to strengthen compliance and audit readiness, showing exactly how AI-powered remediation was applied.

Security and Compliance
Security scanning remains a core component of Transform for .NET. The transformation reports surface CVEs and their fixes, making it easier for teams to trace issues from discovery to resolution. This addition is pitched as particularly useful for regulated industries that need evidence of risk management practices.

Competitive Context
The new report capability comes as Microsoft and GitHub emphasize transparency in Copilot app modernization. Both providers are working to balance automation with developer oversight, but AWS's transformation reports represent a more explicit effort to document the AI's decision-making trail. With Microsoft targeting Azure and AWS anchoring modernization in its own cloud, the feature sets highlight a growing race to deliver modernization at scale while maintaining compliance and governance standards.
