VS - How To Collapse your Solution Explorer.

You may have notice (or maybe not) that VS'08 often expand the whole Solution Explorer  when you open a solution.

With VS'12 The VS Team added the solution explorer collapse button, but we can add that functionnality to our old VS using a simple VB Macro.

You have to follow some few step and play! 

1. unzip SolutionCollapse.zip (in Users\YOU\Documents\Visual Studio 2008\Projects\VSMacros80 for example)  
2. Open  VS'08 – View – Other windows – Macros Explorer 3)       Dans l’explorateur de macro – Load Macro Project – And select SolutionCollapse  
3. Now in  Tools –Customize  – Keyboard 
1.  in "Show command containing" enter « Collapse », Scroll the results to find "Macros.SolutionCollapse.CollapseAll"
2.  Set a shortcut  (CTRL-M + CTRL-C for example)

Done.
