Question:No IntelliSense in WinUI 3 C++ projects xaml editors, no member listed

[a-M1NG]

NOTHING is listed when I write in the editor.

Also,the setting in Options Statement completion under the XAML tab in Text Editor can not be selected.

Am I missing some key packages or is this a bug?
Everything works well in other C# based projects, including WPF and WinUI3.

Those options are disabled for me too, but I have no issues with C++.

The two things I would suggest are.

1. Close Visual Studio and completely clean your solution. Delete any intermediate and generated directories, this includes directories like x64, ARM64, Release, Debug and Generated Files. You would also want to remove the .vs directory. This .vs directory is hidden, so you may have to show hidden files and folders, but not the system files. After doing this, open the Visual Studio and load your project, and then build it. It doesn't matter if this fails, you just want Visual Studio to generate any metadata.
2. If it isn't installed, try installing the Universal Windows Platform development workload.

Thank you for providing the solution! I appreciate your help in resolving my issue.
Although the first point in your solution did not seem to work, it did have an effect after installing the workload. Thank you again for helping me tackle this issue.
