如果用户尝试访问授权页面，我想将未经授权的用户重定向到登录页面。到目前为止，我是使用本教程编写的。项目建设成功。但是浏览器抛出了这个错误

未处理的异常呈现组件：在“窗口”中找不到“AuthenticationService”

页面卡在授权上

<Authorizing>
  <div class="main">Please wait...</div>
</Authorizing>

所有页面都打印“请稍候...” 我该如何解决这个错误？

应用程序Razor

<CascadingAuthenticationState>
<Router AppAssembly="@typeof(Program).Assembly">
    <Found Context="routeData">
        <AuthorizeRouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)">
            <NotAuthorized>
                <RedirectToLogin />
            </NotAuthorized>
            <Authorizing>
                <div class="main">Please wait...</div>
            </Authorizing>
        </AuthorizeRouteView>
    </Found>
    <NotFound>
        <LayoutView Layout="@typeof(MainLayout)">
            <p>Sorry, there's nothing at this address.</p>
        </LayoutView>
    </NotFound>
</Router>
