I’m building a .NET 8 Blazor WebAssembly app with prerendering (InteractiveWebAssembly). When navigating via links, everything works fine. But if I manually enter a URL (e.g., /login), the server prerenders before WASM loads, causing crashes due to missing client-only services (e.g., ILocalStorageService).

MY SOLUTION=> Delay Rendering Until WASM LoadsInstead of letting the server render pages that need client-only services, I show a loading screen until WASM takes over.

@if (!_isLoaded)
{
    <div id="app-loading">Loading...</div>
}
else
{
    <div class="page">
        <NavMenu />
        <main>@Body</main>
    </div>
}

@code {
    private bool _isLoaded = false;

    protected override async Task OnAfterRenderAsync(bool firstRender)
    {
        if (firstRender)
        {
            await JSRuntime.InvokeVoidAsync("console.log", "Client ready");
            _isLoaded = true;
            StateHasChanged();
        }
    }
}

Is there a better way to prevent crashes while keeping it simple and scalable?
