If you’ve used the Help content in the MSDN Library using Lightweight view, you’re probably familiar with the tabbed code block interface. These tabbed code blocks enable you to easily switch between code examples in various programming languages by clicking on the appropriate tab.

We got feedback from some customers that they were unable to switch from one language to another, even though they had enabled cookies in the internet browser.  The issue was identified and a fix was just released.

Tabbed code blocks require cookies in order to function correctly. If you’re still unable to switch between code tabs, you need to make sure you have cookies enabled in your browser; or you can add www.microsoft.com  to the exception list if you don’t want to enable cookies everywhere.
