https://github.com/microsoft/WindowsAppSDK-Samples/tree/main/Samples/Islands/cpp-win32-unpackaged Hello, I have 3 questions to ask about the above link. 1.Is "WinAppSDK island" in README referring to WindowsAppSDK island 2.Is "WinAppSDK island" in README referring to XAML Islands(https://learn.microsoft.com/zh-cn/windows/apps/get-started/windows-developer-glossary#xaml-islands) 3.Why is C++/WinRT's XAML used instead of WinUI3 if WindowsAppSDK is being used

Hi, sorry for the confusion here.

1.Is "WinAppSDK island" in README referring to WindowsAppSDK island 2.Is "WinAppSDK island" in README referring to XAML Islands(https://learn.microsoft.com/zh-cn/windows/apps/get-started/windows-developer-glossary#xaml-islands)

Firstly, "WinAppSDK" and "WindowsAppSDK" refer to the same thing, in case that wasn't clear.

"WinAppSDK island" is a term we've used in a few places to distinguish Xaml Islands in WinAppSDK/WinUI3 from Xaml Islands using Windows "system" Xaml / WinUI2. "WinAppSDK Island" here specifically refers to the Microsoft.UI.Xaml.Hosting.DesktopWindowXamlSource class. The link you mentioned above is about "system" Xaml, which contains the Windows.UI.Xaml.Hosting.DesktopWindowXamlSource API.

3.Why is C++/WinRT's XAML used instead of WinUI3 if WindowsAppSDK is being used

C++/WinRT is a technology that helps C++ apps to consume WinRT APIs. You can use it to interact with many WinRT APIs, including WinAppSDK APIs. The sample uses C++/WinRT and WindowsAppSDK, which contains WinUI3.

Thanks!
