I would like to start a new instance of a wcf service host from another (UI) application. I need the service to be out of process because I want to make use of the entire 1.4GB memory limit for a 32bit .NET process.

The obvious method is to use System.Diagnostics.Process.Start(processStartInfo) but I would like to find out whether it is a good way or not. I am planning on bundling the service host exe with the UI application. When I start the process, I will pass in key parameters for the WCF service (like ports and addresses etc). The UI application (or other applications) will then connect to this new process to interact with the service. Once the service has no activity for a while, it will shut itself down or the UI can explicitly make a call to shut the service down.

    You can definitely do this:

    • create a console app which hosts your ServiceHost
    • make that console app aware of a bunch of command line parameters (or configure them in the console app’s app.config)
    • launch the console app using Process.Start() from your UI app

    That should be fairly easy to do, I’d say.
