I see it as being handy when you create a new object of some type using reflection, when you don't know the type beforehand.

1. Why do we need "Implicitly typed local variables" (similar to "var" in JS)? Is it created especially for LINQ?? If LINQ is not used in the application, this kinda variable won't be required anymore, isn't it?

2. Let's say I wrote like that "var myvar = 1;". then, C# compiler will assume my variable "myvar" is int, right? Actually, I declared it as long.. What about "int vs uint", "long vs ulong" and "double vs float vs decimal"??

var first = 1U; // uint
var answer = 42L; // long
var big = 1234567890UL; // ulong
var pi = 3.1416; // double
var size = 12.5F; // float
var price = 27.99M; // decimal

var b = new System.Web.UI.HtmlControls.HtmlInputRadioButton();

System.Web.UI.HtmlControls.HtmlInputRadioButton b = new System.Web.UI.HtmlControls.HtmlInputRadioButton();
