SecurityException: Request for the permission of type AspNetHostingPermission failed

Setting up a new developing workstation, when I run the ASP.NET (MVC) application from Visual Studio 2008 I get a SecurityException. Any ideas what might be the problem?

I am accessing the data files over SMB (it's a shared mounted as Z:) and I've given full trust to it by running

caspol -m -ag 1 -url "\\server\share\" FullTrust -exclusive on

The full traceback is:

Server Error in '/' Application.

Security Exception

Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Here's a command which worked for me:

C:\Windows\System32>C:\Windows\Microsoft.NET\Framework\v2.0.50727\caspol.exe -m -ag 1 -url "http://localhost/*" FullTrust

Are you using a virtual directory that points to a remote share?
