title: SignalR WebApp.Start(url) doesn't like other exe's in folder?
body: <p>My WebApp.Start method throws a System.IO.FileLoadException when other exe's are in the same folder.  I have no clue why this is happening and its driving me nuts. Any help is appreciated.</p>
  
  <pre><code>//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 =&gt;
          {               
              map.UseCors(CorsOptions.AllowAll);
              var hubConfiguration = new HubConfiguration
              {                    
                  EnableJSONP = false,                   
                  EnableDetailedErrors = true,
                  EnableJavaScriptProxies = true
              };                              
              map.RunSignalR(hubConfiguration);
          });
      }
  }
  </code></pre>
  
  <p>This was working fine until I threw the service into testing for a production rollout and now it gives the following error.</p>
