为什么在app.razor中无法识别NotAuthorizedContent标记

Question

我正在使用app.razor中的标记在所有页面中指示用户无权显示相同的消息，但是NotAuthorizedContent标记无法识别我

<CascadingAuthenticationState>
<Router AppAssembly="@typeof(Program).Assembly">
    <Found Context="routeData">
        <RouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)" />
    </Found>

    <NotFound>
        <LayoutView Layout="@typeof(MainLayout)">
            <p>Sorry, there's nothing at this address.</p>
        </LayoutView>
    </NotFound>
    <NotAuthorizedContent>
        <h1>Sorry</h1>
        <p>You're not authorized to reach this page. You may need to log in as a different user.</p>
    </NotAuthorizedContent>
</Router>

使用AuthorizeRouteView：

<CascadingAuthenticationState>
    <Router AppAssembly="@typeof(Program).Assembly">
        <Found Context="routeData">
            <AuthorizeRouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)">                
                <NotAuthorized>
                    @if (!context.User.Identity.IsAuthenticated)
                    {
                        <RedirectToLogin />
                    }
                    else
                    {
                        <p>@L["NotAuthorized"]</p>
                    }
                </NotAuthorized>
                
            </AuthorizeRouteView>
        </Found>
        <NotFound>
            <LayoutView Layout="@typeof(MainLayout)">
                <p>@L["NothingAtAddress"]</p>
            </LayoutView>
        </NotFound>
    </Router>
</CascadingAuthenticationState>
