things i've tried:

deleting obj folder , bin folder restart visualstudio 2012 restart sql server restart computer uncheck enable property evaluation , other implicit function calls in debugging options uncheck enable code in debugging options

please help me!

hit pause button in vs see code stuck at. also, can set breakpoint @ code's main entry point , f11 until find (most likely) infinite loop.

if utilize pause approach, can @ callstack figure out got point , might looping/stuck
