Form submit resulting in “InvalidDataException: Form value count limit 1024 exceeded.” In ASP.NET Core

You can change the default formvalue limit using the   FormOptions . If you are using MVC, then you can create a filter and decorate on action where you want to extend this limit and keep the default for rest of the actions. namespace Filter {     using System;     using Microsoft.AspNetCore.Http.Features;     using Microsoft.AspNetCore.Mvc.Filters;     /// <summary>     /// Request Form Size Limit Attribute     /// </summary>     /// <seealso cref="System.Attribute" />     /// <seealso cref="Microsoft.AspNetCore.Mvc.Filters.IAuthorizationFilter" />     /// <seealso cref="Microsoft.AspNetCore.Mvc.Filters.IOrderedFilter" />     [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]     public class RequestFormSizeLimitAttribute : Attribute, IAuthorizationFilter     {         /// <summary>         /// The form options         /// </summary>         private read

In other words, we can say that a Repository Design Patternacts as a middleman or middle layer between the rest of the application and the data access logic. That means a repository pattern isolates all the data access code from the rest of the application. The advantage of doing so is that, if you need to do any change then you need to do in one place. Another benefit is that testing your controllers becomes easy because the testing framework need not run against the actual database access code. With a repository  design pattern introduced, the above figure can be changed to: Why we need   the Repository Pattern in C#? Most of the data-driven applications need to access the data residing in one or more other data sources. Most of the time data sources will be a database. Again, the
