turn on ASP.NET 4.0

This and this has a good article on how to beat this error when running a web site in Visual Studio via IIS:

ASP.NET 4.0 has not been registered on the Web server. You need to manually configure your Web server for ASP.NET 4.0 in order for your site to run correctly, Press F1 for more details.

• Try to turn on everything when prepping IIS7 except for "IIS6 Management Console"
• Open a command prompt as an administrator and type:
  aspnet_regiis.exe -i
  ...at:
  C:\Windows\Microsoft.NET\Framework\v4.0.30319\

DirectCast in VB allows for downcasting!

The last line of C# code here will cause an error:

Cat cat = new Cat();
Lynx lynx = new Lynx();
Cat attemptedUpcast = (Cat) lynx;
Lynx attemptedDowncast = (Lynx) cat;

 
 

But none of the following lines of VB Script are problematic:

Partial Class VBform
   Inherits System.Web.UI.Page
   Dim snake As Snake
   Dim viper As Viper
   Dim attemptedUpcasting As Snake = CType(viper, Snake)
   Dim attemptedDowncasting As Viper = DirectCast(snake, Viper)
End Class
