阅读更多关于 Routing in MVC 6

问题 I have a super simple controller with 2 methods: public IActionResult Users(long id) { return Json(new { name = "Example User" }); } public IActionResult Users() { return Json(new { list = new List<User>() }); } One to select all users and the other to return all users. In web api 2 I could user the following route and everything worked fine: config.Routes.MapHttpRoute( name: "Users", routeTemplate: "v1/Users", defaults: new { action = "Users", controller = "Users" }, constraints: null,

Migrate html helpers to ASP.NET Core

阅读更多关于 Migrate html helpers to ASP.NET Core

问题 I'm converting a project to ASP.NET Core. I need to migrate lots of reusable html helpers, but html helpers do not exist in Core. Some are complex, some simple. Here's a extremely simple example: @helper EditIcon() { <i class="glyphicon glyphicon-pencil"></i> } Note that this is only an example. Point is writing a tag helper for that is gigantic overkill. Same for partials. Same for view components. We're talking about a little snippet of Razor. What is my best option? 回答1: So, seems there

Getting blank pages for error messages with UseDeveloperExceptionPage enabled

阅读更多关于 Getting blank pages for error messages with UseDeveloperExceptionPage enabled

I'm getting blank pages for both when I enter an invalid URL, or when an exception is thrown within my application. I have UseDeveloperExceptionPage() enabled, and I have confirmed that my app environment is in development mode, and that the method is firing. The app works fine, but not having error messages displaying in the browser is frustrating. My Startup.cs Configure method: public void Configure(IApplicationBuilder app, IHostingEnvironment env) { app.UseIISPlatformHandler(); app.UseStaticFiles(); app.UseIdentity(); app.UseMvc(m => m.MapRoute( name: "default", template: "{controller}/

How to set the request timeout for one controller action on IIS and IIS Express

阅读更多关于 How to set the request timeout for one controller action on IIS and IIS Express

I need to increase the request timeout for a specific controller action in my application programmatically in the controller. The best way I have found so far to handle a long running script (if your application simply can't avoid having one) is to firstly create an async handler: public async Task<IActionResult> About() { var cts = new CancellationTokenSource(); cts.CancelAfter(180000); await Task.Delay(150000, cts.Token); return View(); } In the snippet above I have added a Cancellation token to say that my Async Method should cancel after 180 seconds (even though in this example it will

how to include views in asp.net 5 class library nuget package

阅读更多关于 how to include views in asp.net 5 class library nuget package

I'm creating a class library project that will contain some ViewComponents. It is nice that VS 2015 can automatically produce the NuGet package for me, but is there any way that I can make it include content files like .cshtml view files that my ViewComponents will need? Previously I've done packaging with batch files and nuspec files to make it include content, will I have to continue that approach or is there a way to tell VS 2015 about content files to include? Not doable as yet. The feature will be in beta7 来源： https://stackoverflow.com/questions/31412210/how-to-include-views-in-asp-net-5
