Facile Technolab supports businesses running VB.NET applications whether that means keeping a legacy system stable and secure, adding new features to it, or migrating it to C# and ASP.NET Core. Most of our VB.NET work today is modernization: helping companies move off ageing VB.NET codebases without losing the business logic that took years to build correctly.
VB.NET is a stable, supported language but it's no longer where Microsoft's investment or the wider .NET ecosystem is heading. If you're running VB.NET today, you're likely in one of three situations. We work with all three.
Your VB.NET application works and does its job it just needs to keep running securely. We provide maintenance for existing VB.NET systems: bug fixes, security patches, small feature additions, and keeping the application compatible as the underlying .NET Framework and Windows Server versions are updated.
This is the right option if:
This is the most common request we get for VB.NET. The application's logic is sound, but the codebase needs to move to C# usually because hiring VB.NET developers is getting harder, or because C# unlocks access to newer libraries, tools, and frameworks that VB.NET projects can't use as easily.
Our migration approach:
For applications that also need architectural modernization moving from Web Forms or WinForms to a web-based ASP.NET Core application, adding cloud deployment, or restructuring a monolith we combine the VB.NET-to-C# conversion with broader modernization. This is a larger project but addresses the underlying issue: an application that's hard to maintain not just because of language, but because of its architecture.
This typically includes:
We're direct with clients about this: VB.NET isn't going away overnight, and an application that works doesn't need to be replaced just because it's old. But there are specific signs that modernization is worth prioritizing rather than deferring again.
C# and VB.NET compile to the same intermediate language and run on the same .NET runtime — the difference is syntax, not capability. But in practice, C# has become the default language for new .NET development. Most current tutorials, libraries, Stack Overflow answers, and AI coding tools are written with C# as the primary example. Moving to C# means your codebase benefits from a much larger pool of current resources, documentation, and available developers — without changing the underlying platform you're already running on.
We work with the current, supported versions of the .NET ecosystem. Here's what a typical Facile Technolab ASP.NET Core project looks like under the hood:
CloudMicrosoft Azure (primary), AWS
| Source language: | VB.NET (.NET Framework 4.x, legacy VB6 where applicable) |
|---|---|
| Target language: | C# 12 (.NET 8) |
| Conversion tools: | Custom conversion tooling + manual review (we do not rely solely on automated converters) |
| UI migration: | Web Forms / WinForms → ASP.NET Core MVC, Blazor, Razor Pages |
| Data layer: | ADO.NET → Entity Framework Core / Dapper Testing: Side-by-side regression testing, xUnit/NUnit for converted logic |
Once a VB.NET application has been migrated to ASP.NET Core, it's often a good opportunity to also modernize the frontend — moving from Web Forms or WinForms to a React, Angular, or Vue.js interface served by the new ASP.NET Core backend. This isn't a requirement of migration, but many clients choose to do both together since the backend work already touches the application's structure.
