I’m creating a web API in Core 3.1 and I have PagingParams model that I will use on many controller actions. The model has PageNumber and PageSize parameters, both of which have a default value:
I’m doing a ASP.NET MVC course. I’m building a REST Web API using ASP.NET WebAPI 2. The application also contains standard MVC 5 views. I’m using DTOs (Data Transfer Objects) to decouple the API from the data model. I’ve made a custom ValidationAttribute that I have applied to a property in my data model, and I’d like to use the same Validation attribute for a property on my DTO as well as a property ViewModel used in an MVC view.
So, I am new in asp.net core, and I am trying to create a new web api in asp.net core. The default controller is Weatherforecast, in other words when I debug the application in the browser the main page is always Weatherforecast. I added a new controller named MainController.cs, and I wrote some simple code there:
Say I had this page in ASP.NET RazorPages:
I am shuffling an IEnumerable using OrderBy and Random() and then selecting some of them using ElementAt.
When the application starts the error occurs
I do not understand why this works sometimes and sometimes not.
I have a .cshtml file that shows a page of my application. In the application, there is a top menu where there are different buttons. The Code is:-
I have a problem with an Asp.Net 5 application I’m currently developing. Essentially it’s an anonymous page with user-attached data, so I’m very much dependant on having a persistent and reliable cookie to identify a calling user. Therefore, I have also checked how I need to configure cookies, and put them on a very long expiration timespan, and made them persistent.
I’m trying to run a simple select statement, and then output the results to a GridView in ASP.NET/ C# WebForms. The database I’m pulling from is a Microsoft SQL Server Database.
