That’s exactly where C++/CLI comes into the picture. You do not have to abandon your current native code, nor do you have to rewrite everything to managed code. That’s C++/ CLI’s single biggest advantage—the ability to reuse existing native code. Reuse existing native code Visual C++ 2005 allows you to compile your entire native code base to MSIL with the flick of a single compilation switch. In practice, you may find that you have to change a small percentage of your code to successfully compile and build your applications.

In C++/CLI, struct and class can be used interchangeably (just as in standard C++), and they follow standard C++ visibility rules for structs and classes. In a class, methods are private by default; in a struct, methods are public by default. 3 19 Type declaration syntax for CLI types CLI type Reference types Declaration syntax ref class RefClass1 { void Func(){} }; ref struct RefClass2 { void Func(){} }; Value types value class ValClass1 { void Func(){} }; value struct ValClass2 { void Func(){} }; Interface types interface class IType1 { void Func(); }; interface struct IType2 { void Func(); }; are both public.

NET programs and adheres to the CLI definition of a managed entrypoint function. The syntax may seem a little confusing right now (because we haven’t yet begun exploring the C++/CLI syntax), but args is essentially a managed array of System::String objects that represents the command-line arguments passed to the application.
