+```csharp
+var builder = WebApplication.CreateBuilder(args);

 The `app.MapGet()` method directly defines an endpoint that handles HTTP GET requests:
 
-[!code-csharp[](../code/mywebapp/program.cs?name=snippet_web_mapget)]
+```csharp
+app.MapGet("/", () => "Hello World!");
+```
 
 `app.MapGet("/")`: Defines a route for the HTTP GET request. The `/` indicates this route responds to the requests made to the root URL of the app. For example, `http://localhost:{port}/`, where `{port}` is a randomly assigned port number assigned in the *Properties/launchSettings.json* file at project creation.
