Action methods on controllers return JsonResult (JavaScript Object Notation result) that can be used in an AJAX application. The JSON result object that serializes the specified object to JSON format.

To configure WebHostBuilder, use the CreateDefaultBuilder method, which provides default settings for app configuration, logging, and Kestrel server. For customization, chain extension methods like UseStartup, ConfigureAppConfiguration, or ConfigureLogging.

If they don’t match or the token is missing, the request is rejected, preventing unauthorized actions from being executed using the victim’s credentials. In modern applications, DI helps maintain clean architecture by separating concerns and enabling modularity. It facilitates easy swapping of implementations for different environments or during testing.
