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
