I'm stuck with only a VS2008 machine this afternoon but I think VS2010 is similar - In the Find in Files dialog there is a dropdown labeled Look In - there is a button to the right with an ellipsis on it - you can choose a set of search folders to search in.

>>>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'
