New .Net MAUI App project throws ‘The name ‘InitializeComponent’ does not exist in the current context’ build errors

I faced the same issue and looks like when I created a ContentPage in VS its still pointing to Xamarin Forms. After changing namespace to MAUI, I updated the Build Action(RightClick on Xaml Page>>Properties>>BuildAction) of XAML Page to MauiXaml and it worked for me.
