WCF Host not running from exe file

Question

Hello,
I got solution which include WinForm app and WFServiceLibrary projects (Both of them sets as a sturtup project)
When I'm running it from the VS2008 the both of them working just fine and the client can access to the host services (my solution).

The problem is that when I'm runing the exe file it seems like my WCF not running in the background, I can't see the "WCF Service Host" and my client unable to recognize the remote host. 

I'm trying to figure how to resolve this problem.

Thanks' in advance..
Lior
