Build and Learn ASP.NET 6.0 Blazor Hands-On - Lifecycle Methods (Code Example) - SetParametersAsync

The video tutorial demonstrates the implementation of the set parameters async method in a Blazor project. It begins with an introduction to the method, followed by steps to create a Blazor project in Visual Studio. The tutorial then explains the set parameters sync method and its role in component lifecycle. It proceeds to build Company and Employee components, illustrating their interaction. The tutorial concludes with a demonstration of parameter updates between parent and child components, highlighting the use of the F12 JavaScript console for debugging.
