Creating a Login Page in ASP.NET Core MVC - A Step-by-Step Guide

If you're diving into ASP.NET Core MVC, one common task you'll face is creating a login page. However, you may find yourself scratching your head when you encounter a "no page found" error message, just like many others have. Fear not, as we’ll guide you through the process to create a seamless login page that works flawlessly!

The Issue: "No Page Found"

When trying to access your login page, encountering an error stating “no page found” is frustrating. This usually points to issues with your routing setup or how your controllers and views are configured. Let’s break down the solution step-by-step to make your login page functional.

Solution Overview

1. Fix the Routing in Startup.cs

This change creates a standard routing pattern, making sure that the framework can find your controllers and actions without hiccups.

2. Redirect Unauthenticated Users

It’s also a good practice to redirect users to the login page if they’re not authenticated. Consider redirecting from the Index action of your Home controller to the Login action of your LoginController.

3. Update Your LoginController

In ASP.NET MVC, it's crucial to have methods to handle both the display of the login form and the processing of submitted credentials. Here’s how you can structure your LoginController:

Final Thoughts

Creating a login page in ASP.NET Core MVC involves setting up a functioning route, handling user input correctly, and implementing a clear structure in both your controller and view. Always remember to check your routing patterns and ensure your HTML structure is in sync with your code logic.

By following these steps, you’ll not only overcome the “no page found” error but also establish a secure and user-friendly login experience. Happy coding!
