What you'll learn

Modern web applications rely heavily on forms, but implementing them correctly in Blazor can be challenging due to differences in render modes and evolving validation approaches. In this course, Forms and Validation in ASP.NET Core 10 Blazor, you’ll gain the ability to build reliable, high-performance forms with modern validation techniques. First, you’ll explore how to create forms using EditForm and input components while binding user input to strongly typed models. Next, you’ll discover how validation works, including data annotations, real-time feedback, and differences between server-side rendering (SSR) and interactive rendering. Finally, you’ll learn how to apply source-generated validation to eliminate reflection, support native ahead-of-time compilation (AOT), and handle complex object validation scenarios. When you’re finished with this course, you’ll have the skills and knowledge of Blazor forms and validation needed to build predictable, performant, and user-friendly form experiences in ASP.NET Core 10.
