Accelerate .NET modernization with agentic AI

AWS Transform for .NET accelerates large-scale modernization from .NET Framework to cross-platform .NET by up to 4x. With the .NET modernization agent, modernization teams can collaboratively execute larger and more complex projects in conjunction with using AI coding tools such as Kiro and AWS Transform custom, remove Windows license dependencies to reduce operating costs by up to 40%, and enhance code quality, performance, and security.

Benefits

Accelerate transformation of .NET applications by up to 4x

Reduce the time required for tedious .NET code analysis, dependency mapping, compatibility assessment and remediation, and refactoring tasks.

Lower operating costs by up to 40%

Reduce Windows Server licensing costs, version upgrades, maintenance, and end-of-support challenges, while also slashing transformation costs across analysis, planning, refactoring, and tooling.

Enhance the quality of .NET porting using generative AI LLMs

Elevate .NET performance through intelligent code transformation, using deep .NET expertise infused in Amazon Bedrock large language models (LLMs) to deliver modernized, cross-platform code with improved security, preserved test coverage, and explainable transformations.

Scale modernization by porting multiple .NET applications together

Modernize multiple .NET applications in parallel with consistency through a unified web experience. Scale team capacity and streamline cross-functional collaboration to tackle large, complex .NET projects with ease.

Transform iteratively in natural language chat

Work alongside the .NET agent, interacting in natural language chat to review assessment findings and explore your options. Customize your transformation plan to a high degree. Review transformation progress at checkpoints and give guidance to refine or retry transformation with course corrections. Iterate until satisfied, and hand-off any remaining work to an AI code companion. You can also transform in autonomous mode for unattended transformation, such as for overnight jobs.

Transform from your preferred AI code companion

Enjoy a unified tool experience as you modernize with AWS Transform from your preferred AI code companion. Transform from Kiro with the AWS Transform Kiro power, or from other AI code companions with AWS Transform MCP server.

How it works

Modernization teams can transform from a unified web experience or IDE through natural language interaction with the .NET domain-expert agent. Under human-in-the-loop supervision, the agent analyzes source code repositories for supported project types, versions, and package dependencies, proposing modernization plans. Upon approval, the agent transforms code, executes unit tests, generates natural language transformation summary, and validates Linux readiness providing continuous milestone and blocker updates. Developers can work with the .NET agent in Visual Studio IDE, interacting to provide guidance, ask questions, review results, and refine the transformation iteratively. Developers can set checkpoints for project-by-project review. For projects partially transformed, AWS Transform provides a transformation summary and next steps for humans to finish the remaining work using AI coding companions such as Kiro or AWS Transform custom.

Impact by the numbers

faster .NET application porting from Windows to Linux

savings in licensing costs

better price performance for your modernized applications to run on AWS Graviton-based instances versus comparable x86-based instances

End-to-end automation

Application discovery and planning

AWS Transform agent for .NET uses deep domain expertise and intelligence from Amazon Bedrock LLM models for optimal inferencing. Through expanded connector support, the agent enables source code integration from GitHub, Bitbucket, and GitLab. The agent analyzes source code repositories to identify .NET versions, project types, and code and package dependencies and provides a pre-transformation assessment report. Based on your codebase, dependencies, and stated business objectives, the .NET agent delivers tailored transformation plans and recommendations.

Code conversion and refactoring

The .NET agent supports transforming a wide range of .NET project types, including MVC, WCF, Web API, Console apps, and unit test projects. It offers repository-level configuration and handles third-party packages, reducing the manual work required to transform .NET Framework applications. The agent transforms .NET Framework applications using a .NET build process and iteratively resolves build errors in a secure, network-isolated environment. The agent commits the transformed code to a new branch in your repository once a task is complete, preserving the original source code.

Testing and validation

The .NET agent autonomously executes unit test projects upon successful transformation and validates Linux-readiness—all with human reviews and approvals. It generates a natural language transformation summary that includes all the changes made to the source code and the build issues identified for easy review and optimizations. When a job is completed, you will also receive an email notification with deep links to the transformed repositories. You can review the branch and merge the code at your convenience.

Automated deployment pipeline generation and environment deployment

A specialized agent deploys transformed applications to specified AWS environments including Amazon EC2 Linux and Amazon ECS for validation and testing, while providing customizable AWS CloudFormation templates and deployment configurations for production use. This enables teams to validate modernized applications in cloud environments and establish automated deployment processes with appropriate oversight and customization capabilities.

Experian

"Experian Data Office faced the complex task of upgrading seven .NET applications from version 6 to 8. Traditional upgrade processes would have required extensive engineering resources, manual code analysis, and significant time investment. By leveraging AWS Transform for .NET, we achieved a remarkable 49-sprint reduction in total effort, reducing each upgrade project effort from 15 to 8 sprints. This represents a 47% productivity gain with 80% automation in code transformation across 687,600 lines of code, allowing us to deliver the projects faster, address vulnerabilities, and maintain consistent results across all seven successful upgrades."

Planet DDS

"AWS Transform enabled us to accelerate and standardize our transformation from .NET 4.6 to .NET 8. We successfully transformed 90% of the codebase, compiled it cleanly, and met all acceptance criteria. A transformation effort originally scoped for three months was completed in less than a week. The tool accurately handled complex changes — such as dependency injection configuration — reducing the need for manual review. This correct-by-default experience gives us the confidence to scale .NET modernization with speed and precision.
