I am developing an API with ASP.NET Core and I am struggling with the exception handling. When any exception occurs, or in any controller where I want to return custom errors with different status codes, I want to return JSON-formatted exception reports. I do not need an HTML in the error responses. I'm not sure if I should use middleware for this, or something else. How should I return JSON exceptions in an ASP.NET Core API? An exception filter (either as an attribute, or a global filter) is what you are looking for. From the docs : Exception filters handle unhandled exceptions, including

How to find all controllers and actions with its attribute in dotnet core? In .NET Framework I used this code: public static List<string> GetControllerNames() { List<string> controllerNames = new List<string>(); GetSubClasses<Controller>().ForEach(type => controllerNames.Add(type.Name.Replace("Controller", ""))); return controllerNames; } public static List<string> ActionNames(string controllerName) { var types = from a in AppDomain.CurrentDomain.GetAssemblies() from t in a.GetTypes() where typeof(IController).IsAssignableFrom(t) && string.Equals(controllerName + "Controller", t.Name,

I'm using ASP.NET Core MVC with CookieAuthentication. Is there a way I can sign all users out at once? I tried resetting IIS - didn't work. I tried deleting all the users' sessions (I'm using a database for session storage) - didn't work. Any ideas? With CookieAuthentication, the cookie is simply an encrypted string containing the user's name, roles, and auxilliary data. In short, it identifies the user , not the session. Killing sessions does not invalidate the cookie. That being said, you can stuff a session identifier or other token in the cookie's auxiliary data, and then validate that

I have an MVC 6 site that has been deployed as an Azure Web App. I have enabled all tracing / diagnostic options in Visual Studio using Server Explorer. I am trying to do remote debugging, but I am only seeing an Error 500 on my browser, and not finding any information (or triggering an error breakpoint) on where exactly the error occurred. I can't find any error trace on the file logs that I get from Azure. How should I troubleshoot Error 500's in an Azure Web App? Adding "CustomErrors": {"Mode": "Off"} to config.json didn't work. For MVC 6 you need to add a web.config file to the wwwroot

I'm trying to port this code over to mvc 6, any help is appreciated, the code compiles but the method is not available in my views on @Html.IsActive . using Microsoft.AspNet.Mvc.Rendering; namespace Blah.Web.Helpers { public static class HtmlHelpers { public static string IsActive(this HtmlHelper htmlHelper, string controller, string action) { var routeData = htmlHelper.ViewContext.RouteData; var routeAction = routeData.Values["action"].ToString(); var routeController = routeData.Values["controller"].ToString(); var returnActive = (controller == routeController && action == routeAction);

I am trying all day to figure out to get the ApplicationDbContext in the ManageController.cs of a default MVC 6 project. I went online and Googled a lot but no one seems to have the same problem as I have with it. It is probably simple but I can't figure it out. Anyone has an idea? Here is what I tried: IServiceProvider service = new IServiceProvider(); var _context = service.GetService<ApplicationDbContext>(); Use constructor injection: public class ManageController { private readonly ApplicationDbContext _context; public ManageController(ApplicationDbContext context) { _context = context; }
