> According to Windows Latest, the high memory consumption is due to the fact that Weather is not a fully native Windows application. Instead, it is essentially an MSN Weather web app built on Microsoft's WebView2 framework.

I wonder how this approach is having such an high reduction in memory usage compared to what’s stated in the article. I would assume both use the exact same WebView here.

The only explanation here that I can think of would be that the “Add an application” starts it under an existing Edge process which shares it’s memory instead of completely isolated.
