Windows Service上的SignalR自托管

Question

I'm wrote a small POC application (console application) on C# (vs2013) that makes: host and clients.

The code of the host side:

string url = "http://*:8900/";

using (WebApp.Start(url))
{
    Console.WriteLine("Server running at " + url);
    lock (just4lock)
        Monitor.Wait(just4lock);
}

It's working only if I'm run my (console) application with "Run as administrator".

Ok, now I'm want to move this code to my Windows Service application. When i'm running the same host code on windows service, I'm getting this error:

An unhandled exception of type 'System.MissingMemberException' occurred in Microsoft.Owin.Hosting.dll

Additional information: The server factory could not be located for the given input: Microsoft.Owin.Host.HttpListener

My service run as "Local System account". I'm not see any option to make it's "run as administrator".

Do you know a way to make SignalR self-hosting works without administrator?

How I'm can make this windows service run as administrator?

Thanks!

Answer 1

我遇到了同样的问题，对我来说，解决方案是将对程序集Microsoft.Owin.Host.HttpListener的引用添加到我的项目中。

Have you tried with a registered Startup object instead?

WebApp.Start<Startup>(url);

then...

class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.MapSignalR();
        }
    }

This works just fine for us...
