title: Replace WCF service library without restarting the service
body: <p>I have a WCF service hosted in windows service and I there are 2 assemblies the host (.exe) and service library (.dll). When the service library is updated we have to stop the service in order to make it possible to replace the library. I would like to have IIS similar functionality, like  to replace the library without restarting the service. 
  Is it possible and how ?</p>
