# Modernizing .NET with AWS Transform
<a name="dotnet"></a>

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
<a name="multiple-experiences"></a>

AWS Transform is available in multiple experiences, including a [web application](dotnet-web-app.md), [Visual Studio IDE](dotnet-ide.md), or [AI code companions via MCP](https://github.com/awslabs/mcp/tree/main/src/aws-transform-mcp-server). Refer to [How to work with the .NET agent](dotnet-work-with-agent.md) for recommendations based on role and scenario.

## Capabilities and key features
<a name="capabilities"></a>

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](https://docs.aws.amazon.com/transform/latest/userguide/custom.html).

AWS Transform for .NET has these capabilities:
+ Connect to source control systems (Azure Repos, Bitbucket, GitHub, GitLab)
+ Assess .NET repositories for modernization and provide a customizable modernization plan
+ Modernize legacy .NET Framework applications to modern cross-platform .NET
+ Update modern .NET applications to later versions
+ Convert Azure cloud-native application code to use AWS equivalents for popular services
+ Validate transformed code with local build verification and unit test execution
+ Produce a transformation report and next steps guidance after transformation

## Supported versions and project types
<a name="supported-versions"></a>

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 | 
| 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, Desktop (WinForms, WPF), Mobile (Xamarin), ASMX web service | 

## Limitations
<a name="limitations"></a>

For more information on quotas and limitations for AWS Transform, see [Quotas for AWS Transform](transform-limits.md).

AWS Transform does not transform the following:
+ 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
<a name="human-intervention"></a>

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
