Call the following function
AddMvc which will instruct the program to add
MVC Services.
builder.Services.AddMvc();
var app = builder.Build();
Configure Routes
Then, the routing is configured.
app.UseRouting();

Displaying a Message from PageModel to Razor Page in ASP.Net Core 8.0 Project
1. Inside the Razor PageModel’s OnGet handler method, the public property named “Message” is set.
public class IndexModel : PageModel
{
public string Message { get; set; }
public void OnGet()
{
this.Message = "This is my First ASP.Net Core 10.0 Razor Page App.";
}
}
2. Then, inside the Razor
HTML Page, the public property
Message is accessed from the Razor
PageModel class and displayed.
@page
@model Core_HelloWorld.Pages.IndexModel
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<h3>@Model.Message</h3>
</body>
</html>
3. Now press F5 to run the application and you should see a message displayed on page in browser.
