To view the code requests in an assembly, use the PermView command line tool.
PermView [/GUI] [/OUTPUT <filename>] <manifest file>
By default, any embedded permission requests will be dumped to the console. If /OUTPUT <filename> is given, output will be dumped to a file in a format compatible with the LM -s option. /GUI will display the permission requests in a graphical window as a tree view.
