[mapguide-users] security exception webconfig.ini

[Kenneth, GEOGRAF A/S]

Ok, then the problem is not with the server, but with the dll calls.
If you right click the Dll files and select properties, are they 
"Protected"? (there is a button to unlock them).

Try to make a simple API import in the code:

[DllImport("kernel32.dll", SetLastError=true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool CloseHandle(IntPtr hObject);

void test()
{
    CloseHandle(IntPtr.Zero);
}

If the call does not fail, the problem is with specific execution 
permissions on the Dll files in your bin folder.
If the call fails, the problem is with your .Net configuration that does 
not allow PInvoke calls.
