.NET on AWS Blog
This article demonstrates how AWS Transform custom automates the migration of legacy VB.NET .NET Framework applications to C#, addressing talent pool and tooling challenges.
- AWS Transform custom is an agentic AI service that performs large-scale code modernization including language migrations and framework upgrades
- Define transformations using natural language; the AI agent analyzes codebase and generates step-by-step execution plans
- Converts VB.NET syntax to C# equivalents: Module to static class, Select Case to switch, Function lambdas to =>, OrElse to ||
- Automatically handles project files (.vbproj to .csproj), namespaces, classes, interfaces, LINQ, error handling, and VB.NET-specific constructs
- Transformation definition is reusable across multiple projects and can be published to registry for team use
- Sample Employee Management System converted 7 VB.NET files to C# with zero build errors and all API signatures preserved
- Optionally follow with AWS Transform Full-Stack Windows Modernization to port C# .NET Framework to cross-platform .NET
AWS Transform custom reduces manual effort and risk in language migrations while maintaining code functionality and enabling modernization paths for legacy applications.
