I have a c sharp dll. How can I make it usable in other languages, such as PHP or Delphi?

Question

I have a dll developed in C Sharp. How can I make it usable in other languages, such as PHP or Delphi?

I cannot find any solution to this problem yet. Isn't there any easy way of doing this?

If Delphi can understand COM, then you can make a COM wrapper around the .NET DLL.

I am doing this now for an older IDE which doesn't understand .NET, but it understands COM so I am able to use the latest .NET features in my older applications.
