How does C# to VB.NET handle void methods?

C# `void` methods are mapped directly to VB.NET `Sub` procedures, while methods with return types are mapped to `Function ... As ReturnType`.

Does the converter translate generic collections like List ?

Yes! C# generic syntax `List ` is translated into VB.NET `List(Of String)`, and vice-versa.

Modernizing & Porting .NET Applications Between C# and VB.NET

Both C# and Visual Basic .NET compile down to the identical Common Intermediate Language (CIL) executed by the .NET Common Language Runtime (CLR). While modern enterprise developments default to C#, millions of line-of-business enterprise systems are written in legacy VB.NET. Cross-converting between the two languages is critical during modernization sprints.

Core Syntactic Differences

Procedures vs Methods: C# methods that return nothing are typed void Method() { ... }, whereas VB.NET distinguishes between non-returning Sub Method() ... End Sub and returning Function Method() As T ... End Function.
Generics Syntax: C# uses angle brackets (List<string>), while VB.NET uses parenthesis with the Of keyword (List(Of String)).
Variable Declaration: C# uses var x = 10; or explicit type declarations; VB.NET uses Dim x As Integer = 10.
