Ugh. I don't denigrate the talent and effort that went into C++/CLI -- it is a valiant (and largely successful) effort to integrate the CLI programming model into C++. But it buys little expressive power over C#, at the cost of a much more complex syntax. Unless you're a language fanatic or are looking to create a CLI interface to unmanaged C++, you'd be best off avoiding it entirely in favor of C#.
