I looked all over for an extension that lets you select the folder(s) you want to search in and brings up the Find in Files dialog. I'm surprised if I'm the first to write one....

Select one or more folders in the Solution Explorer, select right-click, and choose the "Find in Selected Folder(s)" menu item. This will open the "Find in Files" dialog with the selected folders already entered in the "Look in:" field.
