In visual studio 2013 after publish a new projet to azure cloud I try to attach the debug but get this error :

Steps:
- New project : Azure cloud Service
- Add worker only
- Publish to my azure account with 'remote debugging' enabled
- visualstudio/server explorer/azure/cloudservice click right on the instance of worker role => attach debugger
- Attach to the process "WaWorkerHost.exe"
then I get the error.. Any idea ? thank you
