Hello World in Visual Basic .NET

Our first program will print the classic “hello world” message. Here’s the full source code.

Module HelloWorld
    Sub Main()
        Console.WriteLine("hello world")
    End Sub
End Module

To run the program, save the code in HelloWorld.vb and use the Visual Basic command-line compiler.

$ vbc HelloWorld.vb
$ HelloWorld
hello world

Sometimes we’ll want to build our programs into executables. Visual Basic can compile the code directly into a .exe file.

After running the vbc command, you will have an executable named HelloWorld.exe:

$ vbc HelloWorld.vb
$ ls
HelloWorld.exe    HelloWorld.vb

We can then execute the built executable directly.

$ ./HelloWorld.exe
hello world

Now that we can run and build basic Visual Basic programs, let’s learn more about the language.
