Need help on using weakreferences.

Question

Hi Team,

I have received an answer for my one of the question(below is the link).

https://learn.microsoft.com/en-us/answers/questions/1320983/need-notification-for-all-the-consumers-when-there

I need help here on the code which is written in the above link, i need to implement a weak reference(whoever uses get and set method) and also i need to know how to do a call back (invoke callbackOnSettingChanged in NotifySettingChanged method).

Answer 1

you just define a delegate and invoke in the notify routine:

not sure your use of weak reference. typically used with a cache. maybe you wanted weak delegate:
