There is a difference in operators when a C# developer has to do VB.NET

For example: && vs And.

THEY ARE NOT THE SAME. The && equivalent in VB.NET is AndAlso

If you do this:

Sub Main()
    Dim result = Part1() And Part2()

    Console.ReadLine()
End Sub

Function Part1() As Boolean
    Console.WriteLine("Part 1")
    Return False
End Function

Function Part2() As Boolean
    Console.WriteLine("Part 2")
    Return True
End Function

What do you think it prints?

If And would behave like && in C# it would print

Part 1

But unfortunately BASIC is different (sigh), it prints

Part 1

Part 2

This can be solved by using AndAlso, which is the short circuited version of And.
