Compile and run VB.NET code online instantly with HCODX. Our free cloud-based VB.NET compiler supports real-time execution, standard input, syntax highlighting, and code download. No installation or configuration required. Start coding in VB.NET now.
Run VB.NET instantly without installing any IDEs or configuring environments. Our cloud-based VB.NET handles libraries, runtimes, and dependencies automatically so you can focus on writing code.
Whether you are studying algorithms in VB.NET, practicing data structures in VB.NET, or exploring functional programming, our tool provides real-time stdout/stderr feedback with interactive standard input support.
HCODX is a free online compiler and code runner: write code in your browser, execute it on a cloud sandbox, and interact with your program through a live terminal. Students use it for coursework and interview practice; developers use it to test snippets in 85+ languages without setting up a local environment.
This page runs VB.NET on the modern cross-platform .NET runtime, the same unified platform that succeeded .NET Framework, giving Visual Basic code access to current base class libraries and runtime performance improvements. Microsoft keeps VB.NET supported on modern .NET for console and library workloads, which matters to the large installed base of enterprise VB systems being migrated forward from Framework 4.x. If you are checking how your code behaves on the contemporary runtime rather than Mono, this is the variant to use. Your program executes in a live terminal: compilation output streams first, then the process runs and Console.ReadLine stops to collect the text you type in real time.
Imports System.Collections.Generic
Module Program
Sub Main()
Console.Write("Enter a temperature in Fahrenheit: ")
Dim f As Double = Double.Parse(Console.ReadLine())
Dim c As Double = (f - 32) * 5 / 9
Console.WriteLine($"{f}F = {c:F1}C")
Dim scores As New List(Of Integer) From {72, 88, 95, 61}
scores.Sort()
Console.WriteLine("Sorted scores: " & String.Join(", ", scores))
Console.Write("Add another score: ")
scores.Add(Integer.Parse(Console.ReadLine()))
Console.WriteLine($"Average is {scores.Average():F2}")
End Sub
End ModuleThe .NET-runtime variant matters most to teams migrating legacy Visual Basic applications from .NET Framework to modern .NET, who need to verify that string interpolation, LINQ methods like Average, and collection initializers behave identically on the new platform. It also serves students in courses standardized on current .NET SDKs, and developers comparing Mono versus modern-runtime behavior for the same snippet. Because startup, number formatting, and library surface match today's production .NET, results here reflect what a freshly deployed console app would do. HCODX is a free online VB.NET editor, runner and interpreter — an IDE-grade compiler and playground to write and run code online, execute code with live output and live preview, no downloads or web server required.
Yes. The runtime makes no difference to interactivity: the page attaches a live terminal to your process, so Console.ReadLine suspends execution mid-program and resumes with the line you type. You can interleave prompts, parse numbers with Double.Parse or Integer.TryParse, and loop until input validates, just like in a local dotnet run session.
The plain VB.NET page compiles with the Mono toolchain, while this one targets the modern cross-platform .NET runtime that superseded .NET Framework. For basic console code the results usually match, but newer base class library methods, string interpolation formatting details, and performance characteristics follow current .NET behavior here, making it the better reference for migration checks.
No. Each run compiles one standalone source file without a project system, so NuGet restore, multi-file solutions, and app configuration files are unavailable. The base class library itself is rich, including generic collections, LINQ extension methods, DateTime, and formatting APIs, so most console-level tasks and coursework run unmodified.
