问题 I have Organizations that login to an asp.net website and when each member logs in I add their ConnectionId and OrganizationId to a static ConcurrentDictionary named OrganizationMembers in a SignalR Hub OnConnected override. I do this so I can send data to a page callback function that contains data relative only to that Organization (SignalR Group). The OrganizationId will represent the SignalR Group that I send data to. Also in the OnConnnected method, I add the OrganizationId and

问题 Is there an efficient way to download a file and save it on disk in a "background" way without blocking the current execution of an action in a mvc controller? Currently I have the following example code working: public ActionResult Index() { InitiateDownload(); var model = GetModel(); return View(model); } private void InitiateDownload() { Task.Run(() => DownloadAndSaveFileAsync()).ConfigureAwait(false); } private async Task DownloadAndSaveFileAsync() { var response = await GetResponse();

问题 I have a database with two tables. Countries and Cities where each city has a relation to a spesific country. In my ASP.Net Web API I can get a list of countries by a GET request to http://example.com/api/countries to run the CountriesController. And I can get details about a country by http://example.com/api/countries/1. If I want a list of all cities for a country the REST query URL should be http://example.com/api/countries/1/cities? And details for a City http://example.com/api/countries

问题 I'm trying to use model binding feature of asp.net 4.5. I'm using Repeater control, seting ModelType property on it, but as soon as I run the application, I'm getting parser error, which states, that Repeater doesn't have ModelType public property.

问题 We recently upgraded our project from MVC 3 to MVC 4. We are targeting the .NET 4.0 framework, and our web app is 32-bit due to some references we have to include. The problem we are having is that we converted our bundling / minification from Chirpy to the built-in ASP.NET bundling. The site runs with no problems on 32-bit servers, both Windows Server 2003/IIS 6 and 2008/IIS 7.5 running ONLY .NET 4.0, and our 64-bit development machines. The bundling / minification works fine on all of the

问题 In an ASP.NET 4.5 MVC 4 Web API project, I want to add a custom HttpMessageHandler .

问题 Regarding ASP.NET 4.5's new System.Web.Optimization / Microsoft.AspNet.Web.Optimization: Can anyone explain the difference in the use of bundling resources using the BundleConfig.cs class file as opposed to the bundle.config xml file? I've seen some articles showing bundling both js and css in BundleConfig.cs, while others showing bundling js in BundleConfig.cs and css in bundle.config. I guess I don't understand #1) why you wouldn't just do them both one particular way for simplicity - and
