Calling Haskell from .Net application

Dear all, I'm new in Haskell. I need to port a haskell application written by someone else to be called by a .Net C# application. I know how to call C++ DLL from C#. However, please kindly advise me how to convert Haskell code to DLL or at least how to write a DLL(in C++) to call haskell code ? Any help will really be appreciated. Best Regards, David
