Exception Details: System.Security.SecurityException: Request for the permission of type ‘System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′ failed.

A developer was using AJAXControlToolkit in an application. Not a big deal. Except that it kept throwing that damn exception. You know the one:


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.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′ failed.

I know what you're going to say, but I prefer to not use caspol.exe to set the trust.

There were several other sites on the server using the toolkit that worked fine, without using caspol to set full trust.
