Definition
Visual Basic .NET (VB.NET) is an object-oriented programming language from Microsoft, built on the .NET runtime, designed as the successor to classic Visual Basic with modern language features like inheritance and exception handling.
Overview
Visual Basic .NET is Microsoft's evolution of the original Visual Basic, rebuilt from the ground up to run on the .NET Common Language Runtime alongside languages like C#. Where classic VB was a standalone, largely procedural tool for rapid Windows GUI development, VB.NET is a fully object-oriented programming language with inheritance, interfaces, generics, and structured exception handling, while keeping VB's readable, English-like syntax (`If...Then...End If`, `Dim`, `Sub`/`Function`) that made it approachable for beginners and business developers alike. Because it compiles to the same intermediate bytecode as C# and shares the .NET base class library, VB.NET code can call into and be called from C# projects almost seamlessly, which made it a common choice for teams migrating large legacy VB6 codebases without a full language rewrite. It remains widely used in enterprise line-of-business applications, Windows Forms and WPF desktop tools, and Office automation (VBA is a distinct but related language), particularly in organizations with long-standing VB investments. Microsoft continues to support VB.NET, but new language features increasingly land in C# first, and most modern .NET tutorials, sample code, and community resources default to C#. As a result, VB.NET today functions mainly as a maintenance and modernization language for existing systems rather than a first choice for greenfield development.
Key Features
- Full object-oriented model: classes, inheritance, interfaces, and polymorphism
- Runs on the .NET runtime and shares libraries with C# and F#
- Readable, English-like syntax with keywords instead of braces
- Structured exception handling with Try/Catch/Finally
- Strong integration with Visual Studio's designer tools for Windows Forms and WPF
- Optional strict and explicit type checking (Option Strict / Option Explicit)
- Interoperates directly with C# projects in the same solution
