Error: Request for the permission of type System.Web.AspNetHostingPermission failed

Every so often I have to go into some historical code to try and see what is happening. And every time I make the same mistake, I try to debug the code off my mapped user drive (I do everything in my user drive which is on a network share. And every time, I get the same error:

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.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Note to self, don’t debug from a local drive!
