Re: [Quickfix-developers] FIXML guessing

[<or...@qu...>]

Don't be confused, these are two different message classes.  You've run
into the .NET API for QuickFIX, which is a wrapper over the C++ API. 
Quickfix::Message is a .NET class, while FIX::Message is a C++ class. 
Those calls are not recursive, they are delegating work to another API.
