How to Prevent Double Page Load in Blazor WebApp Without Losing UI Functionality?

[emilsjog]

Hi all,

I have a Blazor WebApp solution based on ABP v9.1, and I came across support forum issue #9130, which describes the problem of the page loading twice. This has been a frustrating experience — the second reload introduces a noticeable delay before the app becomes usable.

I tried the suggestion from @maliming to set @rendermode="InteractiveServer" in App.razor. This does seem to prevent the second reload, and the application appears to run smoothly in general.

However, I noticed that the user menu and the language dropdown stop working unless I use InteractiveAuto or InteractiveWebAssembly as the render mode. So while InteractiveServer improves the load behavior, it breaks essential parts of the UI.

Has anyone found a way to avoid the double page load and keep those UI components functional? Any tips or workarounds would be appreciated.

Thanks!

Can you share an online website URL to reproduce this?
