Modernizing .NET with AWS Transform

The AWS Transform agent for .NET can help you modernize your .NET applications to be compatible with cross-platform .NET. This capability is called .NET modernization. After AWS Transform environment in AWS Transform, you can create a .NET modernization transformation job.

Capabilities and key features

  • Analyze .NET Framework codebases from your source control systems, which includes private NuGet support, identifying cross repository dependencies, and providing an analysis report.

  • Automated transformation of legacy .NET Framework applications to cross-platform .NET, email notifications, and a transformation summary report.

  • Easy integration with the source control platforms (BitBucket, GitHub, and GitLab) to ingest existing code and commit transformed code to a new branch.

  • Validation of transformed code through unit tests.

Supported versions and project types

AWS Transform supports transformation for these versions of .NET:

  • .NET Framework 3.5+

  • .NET Core 3.1

  • .NET 5.x+

  • .NET 8

AWS Transform can transform to these target .NET versions:

  • .NET 8

  • .NET 10

AWS Transform supports transformation of these types of projects (C# only):

  • Class libraries

  • Console applications

  • ASP.NET:

    • Model View Controller (MVC), including front-end Razor Views

    • Single Page Application (SPA) back-ends (business logic layers)

    • Web API

    • Web Forms

  • Unit test projects (NUnit, xUnit, and MSTest)

  • Windows Communication Foundation (WCF) services

  • Projects with provided cross-platform versions for third-party or private NuGet packages. If a cross-platform equivalent is missing or unavailable, AWS Transform for .NET will attempt a best-effort conversion.

AWS Transform can also transform the following project types to modern .NET. This is a preview feature, available only in the US East (N. Virginia) Region.

  • WinForms desktop projects. This is a preview feature, available only in the US East (N. Virginia) Region.

  • WPF desktop projects. This is a preview feature, available only in the US East (N. Virginia) Region.

  • Xamarin mobile projects. This is a preview feature, available only in the US East (N. Virginia) Region.

  • Projects written in VB.NET. This is a preview feature, available only in the US East (N. Virginia) Region.

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

  • Applications written in VB.NET

  • Repositories that do not contain any solutions.

  • AWS Transform will not modify the original repo branches, and can only write to a separate target branch specified in your transformation plan.

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.
