Better language for email polling, C# or C++?

Question

There's currently a small internal debate over what language we should be writing an email polling service.
It is a part of a much broader system. Various accounts will be set up, and emails will be pulled from them and then encrypted and stored in a database.
As it is part of a larger system we are planning on using an ORM such as Entity Framework and have a DAL or C# API to handle all things database. C# .NET has a solid networking API and some mail related stuff already, as well as solid encryption.
Concerns surrounding using C++ include;
Having to write network code from scratch (limited on external library use)
Can not use Entity Framework or the C# database API, would require database code to be repeated in 2 languages allowing for transfer of bugs, more time taken etc..
Encryption.. The clients are going to be .NET and so we want to use .NET encryption from start to finish so that encryption is standardized throughout
Later in the projects life we want to support more than just Pop3 and IMAP, Microsoft provide a managed API for it's exchange web services. To achieve this in C++ is not elegant and not recommended by Microsoft
What are the advantages of using C++ in this scenario if any?

Answer 1

Hi Lee,
first of all: I would choose C# for the task.
That said, C++ does have some advantages:
Better control over memory usage (it's especially easier to vanish sensitive information from memory)
Having to build it up from scratch means you can optimize performance to your specific needs.
I don't see how that would justify adding that much more work-hours though.

Fred
