Building a User Registration System in .NET Core & C#

🚀 My journey into ASP.NET Core: Implementing a User Registration System 🚀

Hey Devs! 👋 I'm learning .NET Core and C# and recently built a user registration system for my web application. I wanted to share my experience and how I implemented the Register method using ASP.NET Core Identity and Entity Framework.

🔧 Technologies Used

• ASP.NET Core MVC for building the web application
• Entity Framework Core for database management
• SQL Server for user authentication storage
• ASP.NET Identity for managing users securely

📌 Implementing the Register Method

Step 1: Create the RegisterViewModel
First, I created a view model to handle user registration inputs.
This ensures validation rules like required fields, email format, and password matching.

Step 2: Register Method in AccountController
Now, let's implement the registration logic inside AccountController.cs.

• Validates the user input
• Creates a new user in the database using UserManager
• Redirects to the login page upon successful registration

Step 3: Register View in Register.cshtml
The frontend part is a simple HTML form in Register.cshtml that posts data to the Register method.

• Uses Razor syntax to bind form inputs to RegisterViewModel
• Implements validation messages via asp-validation-for
• Submits form data to the Register method in AccountController.cs

💡 What I Learned

✅ How to validate user input in ASP.NET Core
✅ How to register users using UserManager<>
✅ How to secure passwords with ASP.NET Identity
✅ How to connect the frontend with backend logic
