Discussion: [Best approach for creating custom controls for WinUI]

What is the best approach for creating custom control? Is it good to develop controls in C# or C++. Any guidelines regarding the same will be useful?

It really depends on what you are trying to do. If you want the control to be usable by native components/apps you would probably want the control to be written in c++, otherwise loading your winrt component would require that the app load the CLR which is a non-starter for a lot of native apps. You can see controls written in C++ in this repro, and controls written in c# in the Windows Community Toolkit.

@StephenLPeters I'm working on creating scheduler control with day, week views similar outlook. I'm currently analyzing whether to start, using in Class Library (WinUI in UWP) or C++/WinRT. I want my custom control to work with WinUI for UWP and also WinUI for Desktop.

1. Whether developing the control in C++/WinRT will have performance benefits over developing custom control in Class Library (WinUI in UWP)?
2. If i develop control in C++/WinRT, how it can be consumed in WinUI in Desktop application? I'm new to WinUI.
