VB.Net was released in 2002 as Microsoft's modernization of Visual Basic 6 onto the .NET runtime. It compiles to the same IL as C# and uses the same standard library — the difference is syntax style (English-like vs. C-family).

Module Program
    Sub Main()
        Console.WriteLine("Hello, VB.Net!")
    End Sub
End Module

• Module Name ... End Module — a static container for code
• Sub Main() — entry point. Sub (subroutine) returns nothing; Function returns a value
• Statements end with newlines, NOT semicolons. Continuation: _ at end of line
• Everything is case-insensitive — console.writeline works the same
• Comments: ' (single quote) runs to the end of the line
• Strings use " only. A ' never opens a string — it opens a comment, so Console.WriteLine('hi') silently becomes a comment and prints nothing

Every executable line lives inside Sub Main. There are no top-level statements: text typed above Module Program is not output, it is parsed as code, and the compiler answers with error VBNC30203: Identifier expected.

Reading stdin: Console.ReadLine() returns a string. Convert with Integer.Parse(s), Double.Parse(s), or CInt(s).

A note on this course's compiler

The grader runs Mono's vbnc, a VB.NET 9-era compiler. It accepts everything above, but it predates two features you will meet in newer VB code: interpolated $"..." strings and lambda expressions (Function(x) x * 2). Lessons flag those where they come up; exercises never need them.

Your exercise

Replace the comment inside Sub Main with a Console.WriteLine call that prints the greeting. The most common way to fail this one is to type the expected output into the editor instead of the code that produces it — the editor holds a VB program, not a text file.
