Global.asax.vb file. (Line numbers are included for reference only.)
01 Shared Sub RegisterRoutes(ByVal routes As RouteCollection)
02
03 routes.IgnoreRoute("{resource}.axd/{*pathInfo}")
04
05 routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
New With {.controller = "Home", .action = "Index", .id = ""}
)
06 End Sub
You implement a controller named HomeController that includes methods with the following signatures.
Function Index() As ActionResult
Function Details(ByVal id As Integer) As ActionResult
Function DetailsByUsername(
ByVal username As String) As ActionResult
You need to add a route to meet the following requirements.
The details for a user must be displayed when a user name is entered as the path by invoking the
DetailsByUsername action.
User names can contain alphanumeric characters and underscores, and can be between 3 and 20
characters long.
What should you do?

routes.MapRoute(
"Default",
"{controller}/{action}/{username}",
New With {.controller = "Home", .action = "DetailsByUsername",
.username = ""},
New With {.username = "\w{3,20}"}
)
C. At line 04, add the following code segment.
routes.MapRoute(
