We implement a log information to our database. I will use a Filters (IActionFilter) functionality for it. I wrote the following class: public class ActionFilter: Attribute, IActionFilter { DateTime start; public void OnActionExecuting(ActionExecutingContext context) { start = DateTime.Now; } public void OnActionExecuted(ActionExecutedContext context) { DateTime end = DateTime.Now; double processTime = end.Subtract(start).TotalMilliseconds; ... some log actions } } Then I have added the following code to the Startup.cs: services.AddMvc(options => { options.Filters.Add(typeof(ActionFilter)); })

I'm trying to make a form that i could save a file(image) , but it shows me an error: InvalidOperationException: The property 'Product.Image' is of an interface type ('IFormFile').

Apply I dont know how to fix it , here's the code: Product.cs public class Product { public Product() { OrderDetails = new HashSet<OrderDetails>(); } public int Id { get; set; } public string Name { get; set; } public string Description { get; set;

I am trying to restrict user to click back button after Login/Logout into the application. If the user is logged in into the application, then after clicking on back button Login view should not be displayed and if user is logged out from the application then clicking on back button LogOff view should not be displayed.

It seems like the PagedList.Core does not contain the extension method for Html helper, so I cannot use the code below: @Html.PagedListPager(Model, page => Url.Action("Index", new { page }), PagedListRenderOptions.MinimalWithItemCountText) I was able to successfully implement the paging in previous version of MVC, but it does not work in ASP.Net Core. Below I have attached IL Dasm reference. Am I missing something, or is there any other way to implement that? PagedList.Mvc: PagedList.Core.Mvc: I should follow the Instructions of the new version, it is a little different from previous version.

I have an ASP .NET Core self-hosted project. I am serving up content from a static folder (no problem). It serves up images cross-site without issue (CORS header shows up).

I have the following CORS policy set up in my Startup.cs: public void ConfigureServices(IServiceCollection services) { services.AddCors
