SignalR WebApp.Start (url) doesn't like other exes in folder?

My WebApp.Start method throws System.IO.FileLoadException when other exes are in the same folder. I have no idea why this is happening and it drives me crazy. Any help is appreciated.

//Calling webapp.start
string url = "http://*:8080/";
SignalRServer = WebApp.Start(url);


//My Owin Startup Class
class Startup
{
    public void Configuration(IAppBuilder app)
    {            
        // Branch the pipeline here for requests that start with "/signalr"
        app.Map("/signalr", map =>
        {               
            map.UseCors(CorsOptions.AllowAll);
            var hubConfiguration = new HubConfiguration
            {                    
                EnableJSONP = false,                   
                EnableDetailedErrors = true,
                EnableJavaScriptProxies = true
            };                              
            map.RunSignalR(hubConfiguration);
        });
    }
}

This worked fine until I dropped the service into production testing and now it gives the following error.

System.IO.FileLoadException: Could not load file or assembly "AutoServiceController, Version = 1.0.5270.19403, Culture = neutral, PublicKeyToken = null" or one of its dependencies.

This seems to fix the problem, although I can't tell you why .... If anyone out there can explain why this fixes the problem, please let me know!

The startup class is not named above. Replaced the call to WebApp.Start (url) with this.



            string url = "http://*:8080/";
            StartOptions options = new StartOptions();
            options.Urls.Add(url);
            SignalRServer = WebApp.Start(options, builder =>
            {
                builder.UseCors(CorsOptions.AllowAll);
                builder.MapSignalR("/signalr", new HubConfiguration
                {
                    // You can enable JSONP by uncommenting line below.
                    // JSONP requests are insecure but some older browsers (and some
                    // versions of IE) require JSONP to work cross domain
                    EnableJSONP = false,

                    // Turns on sending detailed information to clients when errors occur, disable for production
                    EnableDetailedErrors = true,
                    EnableJavaScriptProxies = true
                });
                builder.RunSignalR();
            });

I recently had the same problem. For people from the future:

You just need to specify your Run class. This would solve the problem:



string url = "http://*:8080/";
SignalRServer = WebApp.Start<Startup>(url);
