c# - WaitHandleCannotBeOpenedException occured in System.dll -

-

i getting warning when trying run project in debug mode.

in previous projects, when have gotten warning, visual studio typically points me specific line of code.

but in case, have no idea how respond warning.

what steps should take debug/fix warning?

enter image description here

there nothing need go debug menu exceptions option , uncheck "thrown" option.

see on exception dialog listed first chance exception. first chance exception sent notify debugger. second change exception send application handle.

all happening have option "thrown" option enabled , visual studio pointing code throw occurred, inside of system dll, not surprising @ all.
