To declare an object in JS i can simply do the following:
var house = new Object();
house.window="square"
house.color="green"
In asp.net (VB) if i try doing the same
Dim house = new Object()
house.window="square"
i get an error: System.MissingMemberException: Public member 'window' on type 'Object' not found.
Do i have to create a house class before i can reference house.window? Is there no way to do it without creating a class?
