问题 I'm quite new to MVC coming from windows forms and 3 tier architecture. I'm trying to figure out using cascading dropdownlists (DDL) populated from database.

问题 I just updated my project to MVC 5.1 from MVC 5. The main web.config file got updated automatically, but web.config s under main View and Areas folders weren't changed. I suspect that's why now I lost both intellisense and resharper support for my actions, controllers and areas. Does anyone know correct web.config content for MVC 5.1 Views? Just replacing 3.0.0.0 to 3.1.0.0 and 5.0.0.0 -> 5.1.0.0 did not solve the issue. It happens in both Visual Studio 2012 and 2013 Professional. 回答1: Found

E.g. something like this: public class ErrorController : Controller { public ViewResult NotFound () { return View(); } public ViewResult Forbidden () { return View(); } public ViewResult

问题 I have what I believe is a standard usage of IMemoryCache in my ASP.NET Core application. In startup.cs I have: services.AddMemoryCache(); In my controllers I have: private IMemoryCache memoryCache; public RoleService(IMemoryCache memoryCache) { this.memoryCache = memoryCache; } Yet when I go through debug, I end up with multiple memory caches with different items in each one. I thought memory cache would be a singleton? Updated with code sample: public List<FunctionRole> GetFunctionRoles() {

问题 I am using ASP.NET MVC5 and Identity 2.0 (beta). It is possible for users to change the username? I am trying using UserManager.UpdateAsync method throws an exception. Regrads, Fran. 回答1: Yes it is possible using the UpdateAsync method but you need to ensure that you update both the email and username fields. var user = userManager.FindById(userId); user.Email = email; user.UserName = email; var updateResult = await userManager.UpdateAsync(user); This method works successfully for me 回答2:
