title: Semantic Logging IsEnabled si always false?
body: <p>I'm using SLAB out-of-process to log ETW events in my applications.</p>
  
  <p>Today I have a problem within WCF services hosted Under WcfTestClient.exe</p>
  
  <p>When I put breakpoint into WriteEvent methods of my EventSource inherited class, IsEnabled() return false !!!
  So no event is written to my console log out-of-process :(</p>
  
  <p>When starting my ConsoleEventSink, I can see my eventSource registered with a LogAlways level and None for MatchAnyKeyword property</p>
  
  <p>Any idea to check what is wrong for this problem ?</p>
  
  <p>Thanks in advance</p>
