c# - type or namespace 'Timers' name does not exist in the namespace 'System' -

I'm sure the answer is not difficult anywhere as much as my mind thinks, but I do not think it's a figure for understanding.

I am trying to set a timer to start a game, along with the tutorials to bring the basics down, I am following the following. I have also created a new project with the EXACT code as a tutorial and I get the same error continuously. Despite the code running completely in the tutorial ...

I appreciate any help And if you can tell me why I messed up and why, instead of correcting the code, I am doing this as a learning project, so I want to know how to stop it in the future. thank you in advanced!

Oh, and I do not know that it matters, but I'm using Microsoft Visual C # 2010 Express.

4 Errors, the same message Lines 10, 66, 67 and 72.

 MSDN tells us that it is from System.dll.  
 
 Namespace: System.Timers  
 Assembly: System (in system.dll)   
 It looks like you  System.dll  are missing the context. Make sure you are referring to:
