I don't want to turn this into a C++ vs. C# thread, but looking at the two languages; I'm wondering which you think is going to become the most popular. I've been programming for almost 10 years, and know both C++ and C# very well. I happen to like both. I like the power of C++, but the less-complex C# is great! I'm going to be starting a new project--a large enterprise application and am trying to choose between C++ and C# as the language. I could use both: C++ for the low-level processes and C# for the business logic, etc... I'm wondering if C++ will someday fade away and be replaced by C# (and future languages to come) or if there is so much invested in solutions already designed by C++ that its going to stick around for a very long time.

Again, I don't want to turn this into a C++ is better then C# war. I'm just looking at this from a business prospective--which would be a wiser choice in the long one. I don't want to write an entire solution in C++ only to have to replace it with C# or another language in 5 years when support for C++ fades.
