How to use a .Net Assembly in Delphi without registering it in the GAC or COM?

i have a simple task:

is it possible to write a Delphi DLL and put a .Net Assembly (with only one interface with 4 methods and one class implementing the interface) besides it and call it from the Delphi DLL?

I mean, can i import the .Net types directly from the .Net assembly (relative filename) if i create a tlb and a delphi unit for the tlb, without registering the Assembly/tlb?

best, thalm

EDIT (what i found):

Most solutions must register at least one dll/tlb for COM. But the most promising thing i found was: Unmanaged Exports from Robert Giesecke, its a Visual Studio project template which lets you write static C# (or whatever .Net language) methods and call them from any unmanaged language, awesome:

class Test
{
    [DllExport("add", CallingConvention = CallingConvention.StdCall)]
    public static int Add(int left, int right)
    {
        return left + right;
    } 
}

EDIT 2: It really works! You can even control the type marshalling, unbeliveable!!!
