C++ .NET basic questions

[Jim H]

If there is a site someone can point me to that answers such basic
questions, rather than taking up support's time posting answers, please let
me know.

I've developed C# .NET, unmanaged C++, and MFC applications. I have not
written any C++.NET apps yet and have some very basic questions.

Are managed C++ programs fully independent executables or are they still
processed at run time like C# and vb.net apps are? Is the finished product
MSIL?

Do C++.NET apps have the same performance as a standard C++ app.

Are managed C++ apps as susceptible to decompiling as C# and vb.net?

Thanks in advance,
jim

processed at run time like C# and vb.net apps are? Is the finished
product MSIL?

Well, your question answers itself. "Managed C++" programs compile to
MSIL by definition.

The thing about the C++ compiler in the VS.Net package is that it is capable
of generating .obj files that get linked to PE formatted executables and
DLLs as VC++ v6 _OR_ it can just as well compile a dialect of C++ to MSIL.
Unlike the other compilers in VS.Net, MC++ is capable of interleaving
managed and native sections in the same module. This capability is why the
language is so well suited to interoperability tasks.

Do C++.NET apps have the same performance as a standard C++ app.

There is _no_ easy answer to such a question. The only answer that is valid
in all cases is the very unsatisfying "it depends".

Are managed C++ apps as susceptible to decompiling as C# and vb.net?

Yes.

Hi Jim,

Additionally to William's answer, if you discussed about the pure managed
C++ application(not the mixed managed/unmanaged code app), I think you can
take it as a .NET assembly directly, just as your C# program. Please take a
look at our MSDN doc for more information about managed C++ programming:

Thank!

Best regards,

I usaly find that the best info sorce is the VC++ Index itself. Other than
that MSDN (part of Microsoft I think) is very good at explaining librarys
that come whith the program. You can find them with a simple search from
the microsoft web site.
