В Visual Studio возникла непредвиденная проблема, которая может повлиять на некоторые функции системы проекта. ⇐ C#

[Anonymous]

Я новичок в программировании, поэтому понятия не имею, что делать. Я работал над проектом веб-приложения blazor и следил за видео, в котором они взяли страницу бритвы из серверного проекта и перенесли ее в клиентский проект, но когда я попробовал, я получил эту ошибку. Visual Studio столкнулась с неожиданной проблемой, и может влияют на некоторые функции системы проекта. Я думаю, что проблема в настройках Visual Studio или что-то подобное может быть чем угодно. И ни одно приложение не запускалось. Спасибо
файлу бритвы, с которым я разговаривал:
@page "/EditVeri"
@page "/EditVeri/{id:int}"
@inject IVeriService VeriService
@rendermode InteractiveWebAssembly

Veri Oluştur


Kodu
@veri.Kodu

Adı
@veri.Adı
Submit


Veri Eklendi

@code {
[Parameter]
public int id { get; set; }
[SupplyParameterFromForm]
Veris veri { get; set; } = new Veris { Adı = string.Empty, Kodu = string.Empty };


async Task HandleSubmit()
{
await VeriService.AddVeri(veri);

await Task.Delay(2000);

}

}

и файл журнала:
