SecurityException error when an application starts from a remote folder

Question

I have an application written in C # that is located on a network share. When I run it from a local drive, everything works fine. When I launch it from remote access, calls like

try
{
    System.Reflection.Assembly.GetExecutingAssembly();
    System.IO.Directory.GetCurrentDirectory();
}

throw a SecurityException 'Request' request.

What causes this, what is the difference between an application that runs locally and one that starts from a remote location?

Answer 1

This is due to CAS ; code running from the local computer has much more trust than code on the intranet, which in turn trusts this code more from the Internet.

IIRC, SP (3.5SP1?), (.. F:) ; :

a: caspol (yeuck)

b: ClickOnce, , .application(yay!)

, ClickOnce ( ).
