Add context menu to VS 2010 solution explorer (display item on solution only)

It is fairly easy to add a context menu item to the solution explorer in VS 2010. But how to display the menu item ONLY on solutio开发者_JAVA技巧n items? Not on project items or something else?

Best regards, D.R.

Use

<Parent guid="guidSHLMainMenu" id="IDM_VS_CTXT_SOLNNODE"/>

and reset the experimental instance before restarting VSX (you can find the reset script in the VS start menu folder)
