Automatically adding namespace

Scenario: Consider that u want to use a class but u don't know under which namespace the class belong.
Here the solution: keep the cursor on the class that u r using and press 'Alt+Shift+F10' a new popup menu will occur which will show the namespace just click on the popup menu the name space will automatically added in the starting of ur code.

Example:
using System;
Regex clsReg = new Regex(); here Regex is a class which comes under System.Text.RegularExpressions namespace but u didnt include it in ur code

now keep the cursor on Regex and press alt+shit+F10 a popup menu will occur like the below image.









then click the using System.Text.RegularExpressions;
now u go and see the starting page of ur code.


Note: This technique will workout for all the built in classes also for the classes which are added in the reference.
