📘 VB.NET
Learn VB.NET from the Basics
VB.NET — the English-like language of the .NET platform — taught from the ground up across 68 lessons. Each lesson checks whether what you typed matches the reference code, giving you instant feedback without ever leaving the page.
What is VB.NET used for?
Visual Basic .NET carries the readable If ... Then / End If style of classic BASIC onto the modern .NET platform. It shares the runtime and libraries with C#, so everything from Windows desktop apps to web services is within reach, and an enormous amount of in-house business software around the world still runs on it. If you can read English, you can very nearly read VB.NET — which is exactly why it remains a gentle first step into the .NET world.
Common uses & related roles:
- In-house business applications
- Windows desktop apps (WinForms/WPF)
- Maintaining long-lived enterprise systems
- Office add-ins and automation
