This approach brings us a possibility to track what exactly we try to convert.

Description

var a = (object)"true";
var b = (bool)a;

It always throws InvalidCastException.

There is safer method:

var a = (object)"true";
var b = (bool)Convert.ChageType(a, typeof(bool));

Even if input is not formatted well to be boolean, then we will get more clear exception:

System.FormatException: String 'false 66' was not recognized as a valid Boolean.

where false 66 is incorrect input.

Motivation and Context

Just to get more clear understanding what is going wrong, and highlight a value returned from server side.
