Modernizing .NET with AWS Transform

AWS Transform for .NET is a generative AI-powered agent that helps you modernize your .NET applications. You can modernize legacy .NET Framework applications to cross-platform .NET, and upgrade .NET applications to later versions.

Multiple experiences

AWS Transform is available in multiple experiences, including a web application, Visual Studio IDE, or AI code companions via MCP. Refer to How to work with the .NET agent for recommendations based on role and scenario.

Capabilities and key features

The scope of the .NET agent is .NET-to-.NET code transformation. If your transformation needs include non-.NET languages and frameworks, such as Web Forms to React, use AWS Transform custom.

AWS Transform for .NET has these capabilities:

  • Modernize legacy .NET Framework applications to modern cross-platform .NET

  • Update modern .NET applications to later versions

  • Integrate with source control platforms (Azure Repos, Bitbucket, GitHub, GitLab)

  • Produce assessment reports and customizable modernization plan before transformation

  • Produce transformation reports and next steps guidance after transformation

  • Validate transformed code with local builds and unit test porting

Supported versions and project types

The .NET agent can transform the following versions, languages, and project types:

Transform from .NET Framework 3.5, .NET Core 3.1, .NET 5.x+ through .NET 10
Transform to .NET 8, .NET 10, .NET Standard (class libraries)
Languages C#, VB.NET (preview feature)
Supported project types Class libraries, Console apps, ASP.NET (MVC, Web API, Web Forms), Unit test projects (NUnit, xUnit, MSTest), Windows Communication Foundation (WCF) services
Preview project types Desktop (WinForms, WPF), mobile (Xamarin), ASMX web service

Limitations

For more information on quotas and limitations for AWS Transform, see Quotas for AWS Transform.

AWS Transform does not transform the following:

  • Blazor UI components

  • Win32 DLLs that don't have core compatible libraries

  • Repositories that do not contain any .NET solutions.

  • Web site projects without a project file (must be converted to a Web application).

Human intervention

During the porting of .NET Framework applications to cross-platform .NET, you may be requested to provide input or approvals in the following scenarios:

  • Set up a connector to your source code and permissions

  • Validate the proposed modernization plan

  • Upload missing package dependencies as NuGets

  • Review and accept the transformed code

More information

You can modernize your .NET code by using either the AWS Transform web application or the AWS Toolkit for Visual Studio.
