The\n  use of the Introspection engine allows\n  for much faster analysis and supports\n  multithreaded analysis. Unlike the\n  Reflection engine from previous\n  versions, in the Introspection engine\n  the assemblies you\'re analyzing are\n  not locked so you won\'t need to shut\n  down FxCop to do a fix and recompile\n  of those assemblies. Finally, the\n  Introspection engine offers a much\n  richer analysis infrastructure\n  compared to the Reflection engine.</p>\n</blockquote>\n'}]
