"Specified cast is not valid. " Exception after Upgrading to 1.1

Tao

I just upgraded .NET framework to 1.1 and VS.Net to 2003 version and
tried to test it out. I created an ASP.NET project using the wizard
and tried to run
it by hitting "F5". I got an exception: "Specified cast is not valid."
The only thing i put there was a "test this." inside the form. What
might be the problem here?

Thanks in advance.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
