Not sure what you mean by 'open projects'
AFAIK both 'Find all References' and 'View Call Hierarchy' will include any references in the current solution.
Only thing I've found that it misses are references in XAML in WPF/Silverlight projects
Hard to see how it could do more (and, again if IIRC, VFP only searches the current project which is really a similar scope)
To me the 'View Call Hierarchy' alone leaves the VFP code reference tool in the shade.
Best,

>>>As Craig suggests 'Find in Files' works. But if you have the code defining the method/property that you are interested in showing in the code window you can:
>(a) Right click on it and choose 'Find all references' or, even better:
>(b) choose 'View Call Hierarchy'

>The latter will show all calls made FROM the method as well as all calls TO. Plus you can track back - ie. all calls to the calls that call the method etc...
