    Question StrongNameIdentityPermission issue

    OK, I'm ready to be ridiculed.

    I've run into an issue when attempting to use strong names. I've followed darwen's example and have it working in a console app, but it fails in a windows app with:
    An unhandled exception of type 'System.Security.SecurityException' occurred in StrongNameTestForm.exe

    Additional information: Request for the permission of type System.Security.Permissions.StrongNameIdentityPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.

    (additional details at the bottom of this message) or if not run in the ide:
    The application attempted to perform an operation not allowed by the security policy. The operation required the SecurityException. To grant this application the required permission please contact your system administrator, or use the Microsoft .NET security policy administration tool.

    If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will be shut down immediately.

    Request for the permission of type System.Security.Permissions.StrongNameIdentityPermission, mscorlig, Version-1.0.50000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.


    If I change the application from a windows app to a console app the call works in main() [before Application.Run(new Form1());], but not in the button click event of the form.

    I've run the .NET Configuration tool (mscorcfg.msc) and tried adding an application and adding a code group (enterprise, machine, and user; new code group with a condition of Strong Name with the public key [the dll, the console app, and the windows app all show the same public key] without specifying the name or version and with the permission set of full trust) all to no avail. I have also tried this on multiple machines.

    Please note that this is failing on my box, not on a remote machine.

    Any thoughts?

    I have attached an 18k zip of the solution that demonstrates this problem.
