Challenge question about exception in c# beginner tutorial

Hey,

In the challenge about exception, i found some misleading code. The question says: Here's how I wrote the code. Now wrap the testing logic with a try/catch and write the message "Value is out of bounds!" to the console if the exception is caught.

This is the associated code: int value = int.Parse(Console.ReadLine());

if (value < 0 || value > 20) { throw new System.Exception(); }

Console.WriteLine(string.Format("You entered {0}",value));

Now i find it weird that in this code we use: Console.ReadLine() and Console.WriteLine()

But when throwing the exception we still do new System.Exception() and not just new Exception().

Isn't console also using the same System namespace as Exception?

Thank you for your time
