Question

Can anyone point me toward an example of using Platform::ArrayReference<T> on the Windows Phone 8? Every attempt I have made has caused a compiler syntax error. It is listed in the documentation as a part of WinRT, but I can’t find anything that conclusively identifies this as desktop-only or not.

I want to use this in my phone app to decrease the number of copies that are going on as I shuffle data between C# and C++, but if this is not allowed, perhaps I’ll just have to live with those copies.

Thank you in advance

I realized that I have been thinking about ArrayReference wrong. When interfacing with C# code, you still need to use Array as your input parameters, but when passing Arrays to other C++ objects or to C# code from C++ code, you can use ArrayReference to wrap a C array in a Platform wrapper.
