Thanks yes I think that documentation is correct for WinUI2 projects but not WinUI3. For WinUI2, you'll need to install the webview2 SDK in the WinRTAdapter project but for WinUI3 / WinAppSDK based apps, the main app project has a reference to WinAppSDK which directly includes its own copy of the webview2 SDK files, so you cannot include a reference to the webview2 SDK in the main app project without seeing the sorts of errors you see above. We'll need to update the documentation thanks.

@david-risney Can you please gives an general steps to make this work? I looked through the webview2 samples and there are no samples about getting WinUI3 with webview2 works. Is this even possible now? I have an urgent need to determine the techonology to use in one of our project.
