In the Client app create a new folder named Components. This is not a special name, we can choose any name we wish.
Once you’ve created the new Components folder, create a file within it named MyFirstComponent.razor and enter the following mark-up.
<div> <h2>This is my first component</h2> </div>
Now edit the Index.razor file. At this point we can either reference the component with a fully qualified name:
Or edit /_Imports.razor and add
@using CreatingAComponent.Client.Components. The using statements here are cascaded into all Razor views – which means the mark-up to use the new component in /Pages/Index.razor no longer needs a namespace.
@page "/" <h1>Hello, world!</h1> <MyFirstComponent/> Welcome to your new app. <SurveyPrompt Title="How is Blazor working for you?" />
Now run the app and we’ll see the following.
