>If the first condition is false, we don't need to evaluate the second. AndAlso only evaluates the second condition if the first is true. According to the linked article, both conditions will be evaluated if you used And. In other words, it seems we always want to use AndAlso in VB.NET instead of And

Not *always* :-}
Consider:

Dim i As Integer = 0
While True
	If (i > 10) AndAlso (System.Math.Max(System.Threading.Interlocked.Increment(i),i - 1) > 10) Then
		Exit While
	End If
End While
