is there any significant difference between c++/cli and c# and i am not meaning some syntax differences.Or is there anything i can't do using c# but can do using c++/cli in a windows forms application if they are the same using c# would be simpler to type wouldnt it?

From bottom up, it would, given off course you are conversant with C#, but your comfort level is not quite the same with C++. The difference? well, there are situations where a lot of mapping or porting is required, like in this problem

Here I'm working with Win32 APIs in C#, something you wouldn't wanna do, sort of a grease monkey's task, hard to keep things tidy. Porting the code which I had originally written in VC++, would be much easier if I was porting it to C++/CLI instead. Other than these few cases however, there seems to be hardly any other grounds where one wins over the other.

Its an interesting query though, do update the forum if you have more to say on this.

There is also no intellisense with C++/CLI, at least in Visual Studio 2010. However, I'm currently learning it because I want to learn C++/CLX for the Metro interface when Windows 8 is RTM and that's probebly the easiest way to do that right now.
