Control Flow — Options
The Control Flow Options panel lets you determine if Try/Catch handlers should be added to methods to further confuse de-compilers. You can also select the maximum number of handlers to be added to a method.
Control Flow — Include and Exclude
The Control Flow Include and Exclude panels let you compose rules that determine which parts of the application will have control flow obfuscation applied to methods. Methods, classes, or entire packages may be selected. Items should be excluded if you are concerned about possible performance issues.
See Graphical Rules Editor for details.
