After called Quit()，Can not find any connectedable devices. about blewinrtdll

Do you get any error message in the bottom-left corner of the window?
Does a rescan work before calling Quit()?
As an alternative, maybe subscribe and unsubscribe are sufficient?

I think there is something wrong with the c# code.

1. when I want next scan, the cancel flag is still true, I must reset it
2. when I do scan、connect、disconnect for loops, it crashed after sometime,because you called Quit() in destructor function.
   I fixed it in my own code, now it works all right. C++ code is very good, no error.
