Enabling MVC and Configuring the Routes
The last important part is to enable
MVC and configure the
Routes in the
Program.cs file.
1. Open the Program.cs file from the Solution Explorer window.

2. Inside the Program.cs, there are two configurations.
Configure MVC Services
Call the following function
AddControllersWithViews which will instruct the program to add
MVC Services.
Configure Routes
Then, the Route is set and the names of the Controller and the Action method are specified.
var builder = WebApplication.CreateBuilder(args);
//Enabling MVC
builder.Services.AddControllersWithViews();
var app = builder.Build();
//Configuring Routes
app.MapControllerRoute(
name:"default",
pattern:"{controller= Home}/{action= Index}/{id?}");
app.Run();
Finally, the Program.cs file will look as shown below.

1. Inside the
HomeController’s Index Action method, a
ViewBag property named “Message” is set.

ViewBag.Message = "This is my First MVC Core 10.0 App.";
return View();
}
}
2. The
ViewBag property is displayed in the
View named “Index” as shown below.
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
