How to use a DLL I created in VB.NET in a delphi app

Okay, I know this isn't a solution but there's no good place to put this. I don't want to put it in the O.P. as an "improvement" because it might not get noticed. And if I post it as a comment it doesn't let me create code tags. So it's here.

Earlier I said I was going to handle this with a console application. Although that works, it's not really the way I want to go. I can't return anything of value from a console application and calling it is not elegant at all. I really need this to be a dll.

So I created an even simpler one. I didn't register it. I can use it in another vb.net forms application just fine because it's easy to create a reference to it.

Here's my dll code (there are no special references, just the default ones for a .net dll):

Public Class Class1
    Public Shared Function returnJunk(inputParam As Int16)
        Select Case inputParam
            Case 1
                Return "one"
            Case 2
                Return "two"
            Case 3
                Return "three"
            Case 4
                Return "four"
            Case 5
                Return "five"
            Case Else
                Return "nothing"
        End Select
    End Function
End Class

Here's my call to it from vb.net

Private Sub SimpleButton2_Click(sender As Object, e As EventArgs) Handles SimpleButton2.Click
    MessageBox.Show(TestDLLJunk.Class1.returnJunk(14))
End Sub

In the calling application, I just right clicked references and browsed to where the compiled dll is. It shows the full path to it in the properties of the dll's reference.

So then I did the same as before in Delphi. This is in my interface uses:

Function returnJunk(inputParam: Byte): string; STDCALL; EXTERNAL 'TestJunk.dll';

Compiling my dll code creates 3 files. I put them ALL in the source folder of my Delphi project and also in the Win32\debug folder just for grins.

And this is my calling code:

procedure TForm1.Button2Click(Sender: TObject);
var
  rj: string;
begin
  rj := returnJunk(4);
end;

Same as before. It compiles but doesn't run. I get the same message as in my O.P.

Then, for the heck of it, I registered it:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe D:\Data\1Work\KT\DelphiTokyoVersion\TokyoConversionTestProjects\TestDLLJunk\bin\Release\TestDLLJunk.dll /tlb /codebase

Same results as before.
