The GGT File Compare tool supports the use of an external diff tool, WinMerge, for inspecting and comparing the XAML code of paired objects. To view the comparison, first ensure that you have WinMerge installed (See Tool Options), right click on the desired row, and select “Diff” from the context menu that appears. Note that this option is available only for rows containing a pair of objects; it is disabled for any row with result value “Unmatched”.
