I am new to programing so ı have no idea what to do. I was working on blazor web app project and ı was following a toturial in the video they picked up the razor page from server projet and put down to client project but when ı tried ı got this error Visual Studio ran into an unexpected problem,and may affect some project system functions. I think problem in the visual studio settings or some thing similar do can be any thing. And No application was not running.thank you
the razor file ı was talkin to :
@page "/EditVeri"@page "/EditVeri/{id:int}"@inject IVeriService VeriService@rendermode InteractiveWebAssembly<h3>Veri Oluştur</h3><br /><EditForm Model="veri" OnSubmit="HandleSubmit" FormName="editVeri"><label>Kodu</label><InputText @bind-Value="veri.Kodu">@veri.Kodu</InputText><br /><label>Adı</label><InputText @bind-Value="veri.Adı">@veri.Adı</InputText><button type="submit" class="btn btn-primary">Submit</button></EditForm><br /><br /><a class="VeriOnay">Veri Eklendi</a>@code { [Parameter] public int id { get; set; } [SupplyParameterFromForm] Veris veri { get; set; } = new Veris { Adı = string.Empty, Kodu = string.Empty };<style></style> async Task HandleSubmit() { await VeriService.AddVeri(veri); await Task.Delay(2000); }}and the log file :
