PHP DOTNET地狱

I'm quite a newbie in PHP and today I discovered DOTNET class.
So I studied manual, surfed the web to find some example and finally wrote my test app:

  1. Created a new DLL using Framework 4.0 Client Profile
  2. Signed the assembly with a strong name key
  3. Marked assembly as COM-Visible

This is the test code I wrote

using System;

namespace CSharpCOM
{
    public class CSharpCOMClass
    {
        public string Base64(string s)
        {
            return Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(s));
        }
    }
}

I compiled the assembly and then registered in GAC (gacutil /if fullpath\CSharpCOM.dll).
If I use gacutil /l CSharpCOM I see

La cache di assembly globale contiene gli assembly seguenti:
csharpcom, Version=1.0.0.0, Culture=neutral, PublicKeyToken=beb607ae770f5750, processorArchitecture=MSIL

Numero di elementi = 1

So everything seems ok.
Then wrote this basic php:

<?php
try{
    $csclass = new DOTNET("CSharpCOM, Version=1.0.0.0, Culture=neutral, " .
                          "PublicKeyToken=beb607ae770f5750",
                          "CSharpCOM.CSharpCOMClass");
    echo $csclass->Base64("Test string"),"
";
} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "
";
}
?>

Whatever I try, loading page hosted in Apache (http://localhost/test01/dotnet.php) I always get

Caught exception: Failed to instantiate .Net object [CreateInstance] [0x80070002] Impossibile trovare il file specificato.
Translation could be: unable to find specified file

Just another thing: using some example (a very basic one here) I read that my assembly (when registered) should be found on %windir%\assembly, but I'm only able to find it in %windi%\Microsoft.NET\assembly\GAC_MSIL\CSharpCOM\v4.0_1.0.0.0__beb607ae770f5750: is this correct? Why don't I have it on first directory?

More: if I create another framework project and try to add a .NET reference I can't find my assembly: is this related to the fact I'm not able to load this assembly from PHP?

Last note: I tried it on Windows XP Professional SP3 32bit and on Windows Seven Enterprise 64bit

UPDATE:
This works:

$form = new DOTNET('System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089', 'System.Windows.Forms.Form');

but this one does not:

$form = new DOTNET('System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089', 'System.Windows.Forms.Form');`  

Is it possible that PHP can load only framework 2.0 assemblies?

    According to this bug report the DOTNET class is not loading .NET 4.0 DLLs. If you're not using any of the new libraries in .NET 4.0 you can target your to .NET 3.5 or lower by opening the project properties and on the "Application" tab change the "Target framework" to ".NET Framework 3.5 Client Profile"

    Now when you install your DLL into the GAC it will get installed into the CLR 2.0 GAC and should be able to be loaded using the DOTNET class in PHP.
