I've got a program where I call a method in an internal class to update the
registry. Something like this:

Program:

using System;
using System.Security.Permissions;
using Microsoft.Win32;

namespace MyNameSpace
{
   public class Program
   {
       [STAThread]
       static void Main(string[] args)
       {
            RegistryClass myClass = new RegistryClass();
            myClass.UpdateRegistry();
       }
   }
}

RegistryClass:

using System;
using System.Security.Permissions;
using Microsoft.Win32;

namespace MyNameSpace
{
   internal sealed class RegistryClass
   {
       internal void UpdateRegistry()
       {
              //Update HKEY_CURRENT_USER
       }
   }
}

I get an error when trying to update the registry saying that I don't have
sufficient permission. So I trird doing like the documentation to the
RegistryKey class says
(http://msdn2.microsoft.com/en-us/library/microsoft.win32.registrykey.aspx)
and changed the program code to:

using System;
using System.Security.Permissions;
using Microsoft.Win32;

namespace MyNameSpace
{
   [assembly: RegistryPermissionAttribute(SecurityAction.RequestMinimum,
ViewAndModify = "HKEY_CURRENT_USER")]
   public class Program
   {
       [STAThread]
       static void Main(string[] args)
       {
            RegistryClass myClass = new RegistryClass();
            myClass.UpdateRegistry();
       }
   }
}

It doesn't work, however. VS complains that "assembly is not a valid
attribute location for this declaration".

Where do I put it then? I think I've tried all possible locations, but to no
avail.

Can anybody tell me what I'm doing wrong? I've done a lot of programs before
that modifies the registry, and this is the first time I've run into a
security problem, so I really don't know why it happens now when it hasn't
happened before....

Cheers,
