How to consume a winrt/c++ lib in WinUI3 Application

Damon Pan 86

Hi MSFT team,

I am trying to consuming a winrt/C++ library (xxx.dll, xxx.winmd) in my application created by VS2022.

If I create UWP/C# application, it's easy to add the reference by: "right click project" -> Add -> reference -> Browse -> "then choose the winmd file" Then it works well.
But if I create WinUI3/C# application, there is no such option to add such reference.

Since I must use WinUI3 App, so Could you please help on how to consume a winrt/c++ lib in WinUI3 Application?

Hello @Damon Pan ,

Have you checked the Castorix31's answer, can using CSWinRT meet your needs?

(the forum for WinUI 3 is https://learn.microsoft.com/en-us/answers/tags/184/windows-app-sdk)

You can use CsWinRT (add Nuget Package) (tested on Windows 10 22H2)
