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

This video tutorial covers the use of onAfterRender and onAfterRenderAsync methods in Blazor, demonstrating how to integrate JavaScript libraries using these lifecycle methods. The tutorial includes setting up a project with necessary folders and files, creating a Razor component, and explaining the code structure. It also shows how to use JavaScript interop to call JavaScript functions from .NET code, specifically initializing the microModal.js library. The video concludes with a demonstration of the project in action.
