c# - Make different editions of an application with single code base -


i have developed application windows desktop (in wpf). let's assume application has 50 features , let's call ultimate application.

i have client demands application 30 features. let's call professional

application 20 features, let's call basic

now, want maintain single source code editions.

my intention users basic edition can't use/see features available in professional edition, , on.

how can achieve this? need use conditional compilation or else?

generally handled based on product key. algorithms generating , reading version depends developer developer.

lets take simple example product keys start prefixing it's version e.g. - ultimate version starts "u" , - uxxxxxxxxxxxx professional version starts "p" , - pxxxxxxxxxxxx , on.

now when application loaded, need enable/disable or show/hide menus based on product key version.

this helpful, when customer wan't upgrade version, need release new product key updated in application & software work unlocked features.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
