"Specified cast is not valid." After Upgrading to Framework V1.1
Tau Liang
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.
