Csharp Blazor Fluent UI DialogService，<；FluentDialogProvider>；错误

我正在使用.net8和Blazor和流畅的UI库，我得到一个错误，即使我在MainLayout的末尾将其添加到App.razor App.razor中，也没有找到任何提供者.

Program.cs

builder.Services.AddHttpClient();
builder.Services.AddFluentUIComponents();

App.razor App.razor

<script src="_content/Microsoft.FluentUI.AspNetCore.Components/js/loading-theme.js" type="text/javascript"></script>
<script src="_content/Microsoft.FluentUI.AspNetCore.Components/Microsoft.FluentUI.AspNetCore.Components.lib.module.js" type="module" async></script>

MainLayout.razor

<FluentLayout>
    <FluentHeader>
        <Header/>
    </FluentHeader>

    <FluentStack Orientation="Orientation.Horizontal" Width="100%" Class="page--container">
        <NavMenu/>

        <FluentBodyContent>
            @Body
        </FluentBodyContent>
    </FluentStack>
</FluentLayout>

<FluentDialogProvider/>
<FluentToastProvider/>
<FluentTooltipProvider/>

Header.razor

[Inject] public IDialogService DialogService { get; set; }

private async Task ToggleThemeHandler()
{
    var dialog = DialogService.ShowDialogAsync<MenuPanel>(new DialogParameters
    {
        Alignment = HorizontalAlignment.Right
    });
    await dialog;
}

MenuPanel.razor

@implements IDialogContentComponent

<FluentDialogBody>
    Menu
</FluentDialogBody>
