    Hello group!

    We're planning to use strong naming for our app and this does indeed
    work fine *if* the app has been registered for fulltrust (w/ caspol).

    Trouble is if it's not *yet* fully trusted. Then, if the app starts
    it bombs immediately with an *ugly* message which the average end-user
    would not understand or appreciate (WTH does it mean?):

    An unhandled exception of type 'System.Security.SecurityException' occurred
    in ...

    *or*

    Common Language Runtime Debugging Services
    Application has generated an exception that could not be handled.
    ...
    Click OK to terminate the application.
    Click CANCEL to debug the application.

    During debugging the debugger doesn't even get as far as executing
    a single line of our code - it's mscoree, on loading the app, that
    issues the 'ugly' msg, right?

    1) What can we do to try/catch this exception so that *we* can issue
       our own 'friendly' msg?

    2) What security permissions are required in AssemblyInfo (something
       that FxCop also keeps complaining about).

    3) How to ensure that once the app gets past 1) (fulltrust=OK) that
       it gets the required privileges ( unmanaged code, R/W registry
       access, R/W file io, ui, reflection )?

    B.t.w. the app uses ADO.NET, JRO *and* JET

    Looking forward to any replies which'll be greatly appreciated
    Many thanks,
      Marius.
