Valid C++, invalid C++/CLI:

int main()
{

gcnew, generic, and nullptr are all reserved words in C++/CLI; nullptr isn't really an issue in C++0x, of course. Herb Sutter blogged about C++/CLI keywords: Under the hood in 2003.

For what it's worth, when I was working on a large mixed codebase (both C++ and C++/CLI), I never ran into syntax issues or trivial issues like this. The giant issue with C++/CLI (in my opinion, of course) is that native code and managed code have completely different resource management paradigms, and it's really easy when writing mixed code to forget which paradigm you need for certain things. I fixed a lot of errors that were due either to an assumption that managed resources were destroyed deterministically or that native resources would be cleaned up by the garbage collector.
