Auto implementation for properties

[axodox]

For our project a certain usecase for WinRT is to forward collections of objects from .Net to C++. We need to use this in both Windows Store and regular desktop apps. I looked at it from multiple angles:

• Using structs is simple, I only need to declare them in the IDL, though I cannot use types like IVector in them.
• Using runtimeclass is a lot of boilerplate code for the properties, since they do not have auto implementation, like in say C#.

My questions:

• Is there a way to make auto properties with IDL / C++/Winrt?
• Or maybe the reverse, doing it in .Net and using it in WinRT? (I know that I can make runtime components for the store with uwp .net core, but how about .Net Framework and the desktop)
• What is the overhead of this solution? Is there a better way to share data between C++ and C# which supports both the store and the desktop? (The data is flowing in one direction, so it can be copied.)

This sounds more like a general question about WinRT. For such questions you're probably better off posting your question (and what you've tried) over on Stack Overflow. This issues page is mostly for tracking issues with the C++/WinRT project itself.

I understand. In any case if there are no auto-properties it would be nice to have them.
