如何通过 RemoteNavigationManager 避免 TaskCanceledException

Question

我有一个 Blazor 服务器应用程序，每隔几分钟我就会在日志中收到以下内容：

Error 12:09:54 [] Microsoft.AspNetCore.Components.Server.Circuits.RemoteNavigationManager - Navigation failed when changing the location to https://louishowe-dev.azurewebsites.net/Identity/Account/Login TaskCanceledException: A task was canceled.
   at Microsoft.JSInterop.JSRuntime.InvokeAsync[TValue](Int64 targetInstanceId, String identifier, Object[] args)
   at Microsoft.JSInterop.JSRuntimeExtensions.InvokeVoidAsync(IJSRuntime jsRuntime, String identifier, Object[] args)
   at Microsoft.AspNetCore.Components.Server.Circuits.RemoteNavigationManager.<>c__DisplayClass13_0.<<NavigateToCore>g__PerformNavigationAsync|0>d.MoveNext()
Error 12:09:54 [] Microsoft.AspNetCore.Components.Server.Circuits.CircuitHost - Unhandled exception in circuit 'GdWjUPhwt9bdljJjyKo0M-eVaVKtacUkhqCtNuwOg-s'. TaskCanceledException: A task was canceled.
   at Microsoft.JSInterop.JSRuntime.InvokeAsync[TValue](Int64 targetInstanceId, String identifier, Object[] args)
   at Microsoft.JSInterop.JSRuntimeExtensions.InvokeVoidAsync(IJSRuntime jsRuntime, String identifier, Object[] args)
   at Microsoft.AspNetCore.Components.Server.Circuits.RemoteNavigationManager.<>c__DisplayClass13_0.<<NavigateToCore>g__PerformNavigationAsync|0>d.MoveNext()

程序继续正常运行，用户没有发现任何问题。但例外通常是坏消息。这是怎么回事？我该如何避免这种情况？

这是 ASP.NET Core 中的一个已知问题，但似乎尚未解决 - 尽管它被标记为已解决。您可以在这里找到现有的问题：aspnetcore Github issues
