Difference between C# and C++ .NET

What's the difference, apart from syntax and semantics, the difference between Visual C++ (using .NET framework) and C#?



If I use .NET framework in C++, will it compile to native code?
If I use .NET framework, will the code automatically become 'managed'.
I'm not clear about managed/unmanaged and CLI stuff.

And lastly, If I use .NET framework in C++, can I add reference to that project in other .NET projects?


Thanks!

Dont know if this helps directly but I asked a question about C++ and the .NET framework a year or so ago, you might get some answers from the replies I received: http://www.vbforums.com/showthread.php?t=516252

How do I write unmanaged C++ .NET code?

library.dll

Code:

---

namespace Library
{
        class testclass
        {
                private:
                        int a;
                        int b;
                public:                       
                        void set_a(int value){a = value;}
                        void set_b(int value){b = value;}
                        int add(){return a + b;}
        };
}

I can't add reference to that DLL in my C# project. It says that DLL has no CLR assembly or something like that.
