C++/CLI article in MSDN

There is certainly a lot more to be said about C++/CLI, never mind the Visual C++ 2005 compiler, but I hope this article has provided you with a good introduction to what it has to offer for programmers targeting the CLR. The new language design provides unprecedented power and elegance to write rich .NET applications completely in C++ without sacrificing productivity, conciseness, or performance.

The following table provides a summary of the most common constructs for quick reference.

Description	C++/CLI	C#
Allocate reference type	ReferenceType^ h = gcnew ReferenceType;	ReferenceType h = new ReferenceType();
Allocate value type	ValueType v(3, 4);	ValueType v = new ValueType(3, 4);
Reference type, stack semantics	ReferenceType h;	N/A
Calling Dispose method	ReferenceType^ h = gcnew ReferenceType; delete h;	ReferenceType h = new ReferenceType(); ((IDisposable)h).Dispose();
Implementing Dispose method	~TypeName() {}	void IDisposable.Dispose() {}
Implementing Finalize method	!TypeName() {}	~TypeName() {}
Boxing	int^ h = 123;	object h = 123;
Unboxing	int^ hi = 123; int c = *hi;	object h = 123; int i = (int) h;
Reference type definition	ref class ReferenceType {}; ref struct ReferenceType {};	class ReferenceType {}
Value type definition	value class ValueType {}; value struct ValueType {};	struct ValueType {}
Using properties	h.Prop = 123; int v = h.Prop;	h.Prop = 123; int v = h.Prop;
Property definition	property String^ Name {     String^ get()     {         return m_value;     }     void set(String^ value)     {         m_value = value;     } }	string Name {     get     {         return m_name;     }     set     {         m_name = value;     } }
