In 3.x, PageView tracking through TrackPageView was removed (https://github.com/microsoft/ApplicationInsights-dotnet/blob/main/BreakingChanges.md#methods) . The recommended migration path was to use TrackEvent instead.

3.x should provide a mechanism to have events show up in the PageView tracking UI in Application Insights
