ASP.NET Core MVC: Handling POST Requests and Form Submissions

Every interactive web application relies on receiving and processing user data securely. If you want to build robust web applications, understanding how controllers handle incoming data is an essential skill. This course teaches you how to manage form submissions and safely process data using ASP.NET Core MVC. You will transition from understanding basic HTTP verbs to building secure, validated endpoints that process user input. By the end of this course, you will be able to handle complex form submissions, validate incoming data on the server, and safely redirect users after successful operations. What you'll learn: - Understand the fundamentals of the HTTP POST protocol and its role in web applications - Create controller actions specifically designed to receive and process form data - Implement robust server-side validation using ModelState and data annotations - Apply the Post-Redirect-Get pattern to prevent accidental double-submissions - Protect your forms against common security vulnerabilities like Cross-Site Request Forgery - Write clean, modern C# code using strongly-typed models and modern binding techniques This course begins with core definitions and the underlying mechanics of web forms. You will then progress through step-by-step written explanations of model binding, validation logic, and secure controller patterns. Every concept is reinforced with practical code snippets and structured text-based exercises. This course is designed for beginner backend developers and web enthusiasts who already know basic C# and HTML. No prior experience with MVC controllers is required.
