Functionality to detect Win32 apps which are installed, deleted or renamed while PowerToys is running (#4960) * Added file system wrapper and interface * added win32program repository which would load store app and also handle new apps being added/deleted * Added event handlers to win32 program repo * added paths to monitor and setting FSWs for each location * Events firing as expected * filter extensions added, events fire as expected * override gethashcode so that duplicates don't show up. OnCreated and OnDeleted events trigger as expected * implemented setter for filters in FileSystemWatcher * Rename adds item but does not seem to delete the previous app * catching an exception when a duplicate item is inserted * Removed notify filter for directory because we only need to monitor files * Added exe programs to be indexed in the desktop and startmenu * created a new class to init FileSystemHelpers instead of main * Added fix for shortcut applications to work as expected while renaming and deleting them * Added wrappers for file system operations * Added some tests * Added all tests for appref-ms and added a condition to search in sub directories * Added tests for Exe applications * Added lnk app tests * Added tests for shortcut applications * removed unnecessary wrappers * override Equals for win32 * removed debug statements * Fixed exe issue * Fixed internet shortcut exception * fixed renaming shortcut apps * Added a retry block for ReadAllLines * capitalized method name - RetrieveTargetPath * made naming consistent, helper variables start with underscore * Added the exception condition back * renamed Win32ProgramRepositoryHelper to Win32ProgramFileSystemWatchers * made win32Program repository variable static * changed list to ilist * disposed file system watchers * make retrieveTargetPath upper case in tests
