name	vbnet

VB.NET

VB.NET is a first-class citizen on .NET, sharing the same runtime/libraries as C#. While C# gets new syntax first, VB.NET remains supported in .NET 8+.

When to Use

• Legacy Migration: Porting VB6 apps to .NET.
• Readability: Specific industries prefer the verbose, English-like syntax (End If).
• Office Automation: Integration with massive Excel/Access logic.

Core Concepts

Case Insensitivity

Dim X and dim x are the same.

Modules

Equivalent to static classes.

My Namespace

My.Computer, My.User. Shortcuts for common tasks.

Best Practices (2025)

Do:

• Use Option Strict On: Disables implicit casting (critical for bugs).
• Target .NET 8: Move away from .NET Framework 4.8.
• Use String Interpolation: $"Hello {Name}".

Don't:

• Don't use On Error Resume Next: Use structured Try...Catch.
