SignalR WebApp.Start(url) 不喜欢文件夹中的其他 exe？

Question

我的 WebApp.Start 方法在其他 exe 位于同一文件夹中时抛出 System.IO.FileLoadException。我不知道为什么会这样，这让我发疯。感谢任何帮助。

//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);
        });
    }
}

在我将该服务投入生产部署测试之前，它工作正常，但现在它出现以下错误。

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

这似乎已经解决了问题，虽然我不能告诉你原因....如果有人能解释为什么这解决了问题，请告诉我！

不再调用上面的启动class。用这个替换了 WebApp.Start(url) 调用。

            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();
            });

我最近遇到了同样的问题。对于未来的人们：

您只需指定您的 "Startup" class。这将解决问题：

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

SignalR WebApp.Start(url) 不喜欢文件夹中的其他 exe？

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

c#

.net
