Hi,
cl.exe has thre modes for compiling C++/CLI:
- /clr
This is the C++ interop mode. It enables native and managed code to coexist
together. Importantly, it is the only clr option that allows you to still
use pointers in your code. This means you can use callbacks and other
places where pointers are typically found in native API's. As both native
and managed code can coexist together you can create a project that uses
both the Windows API and the .Net Framework. These are known as mixed
assemblies in .Net terminology.
- /clr:pure
Will compile all the code to IL and produce a pure .Net assembly. This
means that you can't use native API's from within your code unless you use
the interop methods provided by the .Net Framework, such as P/Invoke or COM
interop.
- /clr:safe
Produces a .Net assembly that is verifiable.

Hi Marlon. At least for the other editions of Visual Studio apart from the
express which i cannot be sure off, you can actually make changes to your
compiler options so that it can compile either native c++ code or
microsoft's cli version of c++ or both. For example, You can turn off the
_T identifier needed to compile character sequences in your code and revert
to the standard CHAR used by native C++. Cheers!

hmm Jamal, correct me if I am wrong, but my understanding is that one
can't compile binary, native win32 executable if they use the cli
part.
Sure visual C can generate binaries for win32, but if you use the
extensions, at least based on what I have understood, the .net
dependencies will be kept ...
In other words I can use visual C to develope binaries in raw c++ but
not in the cli version, using visual c.

Yes, my undrstanding is that C++/CLI is essentially for C++ developers
who want to take advantage of the .NET Framework with the language and
associated features to which they have become accustomed. Microsoft
submitted the language for international standardization, and this has
occurred, so theoretically other software publishers and platforms could
develop compilers for C++/CLI besides Microsoft Visual C++. It is
unlikely that will happen practically speaking, however, because of the
inherent relation to .NET 2.0.
It is noteworthy that Microsoft's compiler can be used to create native
Win32 executables in standard C++ without any .NET dependencies. In
other words, the CLI aspect adds language extensions, but not
requirements for a traditional C++ developer.
